## Get Started
Follow these steps to the coolest experience in error handling
### Add dependency
```yaml
dependencies:
talker: ^4.4.1
```### Easy to use
You can use Talker instance everywhere in your app
Simple and concise syntax will help you with this```dart
import 'package:talker/talker.dart';final talker = Talker();
/// Just logs
talker.warning('The pizza is over 😥');
talker.debug('Thinking about order new one 🤔');// Handling Exception's and Error's
try {
throw Exception('The restaurant is closed ❌');
} catch (e, st) {
talker.handle(e, st);
}/// Just logs
talker.info('Ordering from other restaurant...');
talker.info('Payment started...');
talker.good('Payment completed. Waiting for pizza 🍕');
```
More examples you can get [there](https://github.com/Frezyx/talker/blob/master/packages/talker/example/talker_example.dart)## ⚙️ Customization
Configure the error handler and logger for yourself
```dart
final talker = Talker(
settings: const TalkerSettings(
/// You can enable/disable all talker processes with this field
enabled: true,
/// You can enable/disable saving logs data in history
useHistory: true,
/// Length of history that saving logs data
maxHistoryItems: 100,
/// You can enable/disable console logs
useConsoleLogs: true,
),
/// Setup your implementation of logger
logger: TalkerLogger(),
///etc...
);
```
More examples you can get [here](https://github.com/Frezyx/talker/blob/master/packages/talker/example/talker_example.dart)### Custom logs
With Talker you can create your custom log message types.
And you have **full customization control** over them!```dart
class YourCustomLog extends TalkerLog {
YourCustomLog(String message) : super(message);/// Your custom log title
@override
String get title => 'CUSTOM';/// Your custom log color
@override
AnsiPen get pen => AnsiPen()..xterm(121);
}final talker = Talker();
talker.logTyped(YourCustomLog('Something like your own service message'));
```### Change log colors
Starting from version 4.0.0, you have the ability to fully customize all logs colors. You can set **your own color for any type of logs**. For example, you can choose red for HTTP responses and green for errors—whatever suits your preference 😁
The Map is structured as **{TalkerLogType: AnsiPen}**.
**TalkerLogType** is an identifier for a specific log type (e.g., HTTP, error, info, etc.), and each log type in Talker has its own field in the enum. And **AnsiPen** is model to console colors customization
```dart
final talker = Talker(
settings: TalkerSettings(
colors: {
TalkerLogType.httpResponse: AnsiPen()..red(),
TalkerLogType.error: AnsiPen()..green(),
TalkerLogType.info: AnsiPen()..yellow(),
// Other colors...
},
),
);
```Talker have default color scheme. You can check it in [TalkerSettings](https://github.com/Frezyx/talker/blob/master/packages/talker/lib/src/settings.dart) class
### Change log titles
Starting from version 4.0.0, you have the ability to fully customize all logs titles. You can set **your own title for any type of logs**.
The Map is structured as **{TalkerLogType: String}**.
**TalkerLogType** is an identifier for a specific log type (e.g., HTTP, error, info, etc.), and each log type in Talker has its own field in the enum.
```dart
final talker = Talker(
settings: TalkerSettings(
titles: {
TalkerLogType.exception: 'Whatever you want',
TalkerLogType.error: 'E',
TalkerLogType.info: 'i',
// Other titles...
},
),
);
```Talker have default titles scheme. You can check it in [TalkerSettings](https://github.com/Frezyx/talker/blob/master/packages/talker/lib/src/settings.dart) class
## TalkerObserver
TalkerObserver is a mechanism that allows observing what is happening inside Talker from the outside.
```dart
import 'package:talker/talker.dart';class ExampleTalkerObserver extends TalkerObserver {
ExampleTalkerObserver();@override
void onError(TalkerError err) {
/// Send data to your error tracking system like Sentry or backend
super.onError(err);
}@override
void onException(TalkerException exception) {
/// Send Exception to your error tracking system like Sentry or backend
super.onException(exception);
}@override
void onLog(TalkerDataInterface log) {
/// Send log message to Grafana or backend
super.onLog(log);
}
}final observer = ExampleTalkerObserver();
final talker = Talker(observer: observer);
```You can use it to transmit data about logs to external sources such as **[Crashlytics](#crashlytics-integration)**, **Sentry**, **Grafana**, or your own analytics service, etc.
# Talker Flutter
## Get Started Flutter
Talker Flutter is an extension for the Dart Talker package that adds extra functionality to make it easier for you to handle logs, errors, and exceptions in your Flutter applications.
### Add dependency
```yaml
dependencies:
talker_flutter: ^4.4.1
```### Setup
```dart
import 'package:talker_flutter/talker_flutter.dart';final talker = TalkerFlutter.init();
// Handle exceptions and errors
try {
// your code...
} catch (e, st) {
talker.handle(e, st, 'Exception with');
}// Log your app info
talker.info('App is started');
talker.critical('❌ Houston, we have a problem!');
talker.error('🚨 The service is not available');
```### ❗️ Log messages integrity
Most of flutter logging packages either cut messages in the console, or cant dope colored messages in the iOS console. But Talker is not one of them...Talker uses the optimal method for logging depending on the Operating system on which it runs
But to do this, you need to use the initialization given in the example. Only with TalkerFlutter.init()
As result of this method you will get the same instance of Talker as when creating it through the Talker() constructor but with logging default initialization
## TalkerScreen
Often you need to check what happening in the application when there is no console at hand.
There is a TalkerScreen widget from [talker_flutter](https://pub.dev/packages/talker_flutter) package for this situations.For better understanding how it works check [Web Demo](https://frezyx.github.io/talker) page
|
| | | |
| ------------------------------------------------------------ | ------------------------------------------------------------ | ------------------------------------------------------------ | ------------------------------------------------------------ |
| TalkerScreen | TalkerFilter | TalkerActions | TalkerSettings |### Easy to use
You can use TalkerScreen everywhere in your app
At Screen, BottomSheet, ModalDialog, etc...```dart
import 'package:talker_flutter/talker_flutter.dart';final talker = TalkerFlutter.init();
Navigator.of(context).push(
MaterialPageRoute(
builder: (context) => TalkerScreen(talker: talker),
)
);
```
See more in TalkerScreen [usage example](https://github.com/Frezyx/talker/blob/master/packages/talker_flutter/example/lib/main.dart)## Customization
Starting from version 4.0.0, you have the ability to fully customize your TalkerScreen display. You can set **your own color for any type of logs**. For example, you can choose red for HTTP responses and green for errors—whatever suits your preference 😁
|
| | | |
| ------------------------------------------------------------ | ------------------------------------------------------------ | ------------------------------------------------------------ | ------------------------------------------------------------ |### How to set custom colors ?
To set your custom colors, you need to pass a TalkerScreenTheme object to the TalkerScreen constructor, with a Map containing the desired colors.
The Map is structured as **{log type: color}**. **TalkerLogType** is an identifier for a specific log type (e.g., HTTP, error, info, etc.), and each log type in Talker has its own field in the enum.
```dart
import 'package:talker_flutter/talker_flutter.dart';final talker = TalkerFlutter.init();
TalkerScreen(
talker: talker,
theme: TalkerScreenTheme(
/// Your custom log colors
logColors: {
TalkerLogType.httpResponse: Color(0xFF26FF3C),
TalkerLogType.error: Colors.redAccent,
TalkerLogType.info: Color.fromARGB(255, 0, 255, 247),
},
)
)
```### TalkerScreenTheme
You can set custom backagroud, card and text colors for TalkerScreen with TalkerScreenTheme
```dart
TalkerScreenTheme(
cardColor: Colors.grey[700]!,
backgroundColor: Colors.grey[800]!,
textColor: Colors.white,
logColors: {
/// Your logs colors...
},
)
```## TalkerRouteObserver
Observer for a navigator.
If you want to keep a record of page transitions in your application, you've found what you're looking for.You can use TalkerRouteObserver with **any routing package**
From auto_route to basic Flutter Navigator### Navigator
```dart
final talker = Talker();MaterialApp(
navigatorObservers: [
TalkerRouteObserver(talker),
],
)
```### auto_route
```dart
final talker = Talker();MaterialApp.router(
routerDelegate: AutoRouterDelegate(
appRouter,
navigatorObservers: () => [
TalkerRouteObserver(talker),
],
),
),
```### auto_route v7
```dart
final talker = Talker();MaterialApp.router(
routerConfig: _appRouter.config(
navigatorObservers: () => [
TalkerRouteObserver(talker),
],
),
),
```### go_router
```dart
final talker = Talker();GoRouter(
observers: [TalkerRouteObserver(talker)],
)
```## TalkerMonitor
If you want to check the status of your application in a short time
**TalkerMonitor** will be the best solution for youMonitor is a filtered quick information about http requests, exceptions, errors, warnings, etc... count
You will find Monitor at the TalkerScreen page
For better understanding how it works check [Web Demo](https://frezyx.github.io/talker) page
## TalkerWrapper
In addition
talker_flutter is able to show default and custom error messages and another status messages via TalkerWrapper```dart
import 'package:talker_flutter/talker_flutter.dart';final talker = TalkerFlutter.init();
TalkerWrapper(
talker: talker,
options: const TalkerWrapperOptions(
enableErrorAlerts: true,
),
child: /// Application or the screen where you need to show messages
),
```## More Features And Examples
### Custom UI error messages
In order to understand in more details - you can check this article ["Showing Flutter custom error messages"](https://dev.to/frezyx/showing-flutter-custom-error-messages-109o)
TalkerWrapper [usage example](https://github.com/Frezyx/talker/blob/master/packages/talker_flutter/example/lib/talker_wrapper_example/talker_wrapper_example.dart)
### ShopApp example
See full application example with BLoC and navigation [here](https://github.com/Frezyx/talker/blob/master/examples/shop_app_example)The talker_flutter package have a lot of another widgets like TalkerBuilder, TalkerListener, etc. You can find all of them in code documentation.
## Integrations
In addition to the basic functionality, talker was conceived as a tool for creating lightweight loggers for the main activities of your application
You can use ready out of the box packages like [talker_dio_logger](https://pub.dev/packages/talker_dio_logger), [talker_bloc_logger](https://pub.dev/packages/talker_bloc_logger) and [talker_riverpod_logger](https://pub.dev/packages/talker_riverpod_logger) or create your own packages.
## Talker Dio Logger
Lightweight, simple and pretty solution for logging if your app use [dio](https://pub.dev/packages/dio) as http-client
This is how the logs of your http requests will look in the console
![](https://github.com/Frezyx/talker/blob/dev/docs/assets/talker_dio_logger/preview_new.png?raw=true)### Getting started
Follow these steps to use this package### Add dependency
```yaml
dependencies:
talker_dio_logger: ^4.4.1
```### Usage
Just add **TalkerDioLogger** to your dio instance and it will work```dart
final dio = Dio();
dio.interceptors.add(
TalkerDioLogger(
settings: const TalkerDioLoggerSettings(
printRequestHeaders: true,
printResponseHeaders: true,
printResponseMessage: true,
),
),
);
```## Customization
To provide hight usage exp here are a lot of settings and customization fields in TalkerDioLoggerSettings. You can setup all wat you want. For example:
### Off/on http request or reposnse logs
You can toggle reponse / request printing and headers including
```dart
final dio = Dio();
dio.interceptors.add(
TalkerDioLogger(
settings: const TalkerDioLoggerSettings(
// All http responses enabled for console logging
printResponseData: true,
// All http requests disabled for console logging
printRequestData: false,
// Reposnse logs including http - headers
printResponseHeaders: true,
// Request logs without http - headersa
printRequestHeaders: false,
),
),
);
```### Change http logs colors
Setup your custom http-log colors. You can set color for requests, responses and errors in TalkerDioLoggerSettings
```dart
TalkerDioLoggerSettings(
// Blue http requests logs in console
requestPen: AnsiPen()..blue(),
// Green http responses logs in console
responsePen: AnsiPen()..green(),
// Error http logs in console
errorPen: AnsiPen()..red(),
);
```### Filter http logs
For example if your app has a private functionality and you don't need to store this functionality logs in talker - you can use filters
```dart
TalkerDioLoggerSettings(
// All http request without "/secure" in path will be printed in console
requestFilter: (RequestOptions options) => !options.path.contains('/secure'),
// All http responses with status codes different than 301 will be printed in console
responseFilter: (response) => response.statusCode != 301,
)
```## Using with Talker
You can add your talker instance for TalkerDioLogger if your app already uses Talker.
In this case, all logs and errors will fall into your unified tracking system```dart
final talker = Talker();
final dio = Dio();
dio.interceptors.add(TalkerDioLogger(talker: talker));
```## Talker BLoC Logger
Lightweight, simple and pretty solution for logging if your app use [BLoC](https://pub.dev/packages/bloc) as state management
This is how the logs of your BLoC's event calling and state emits will look in the console
![](https://github.com/Frezyx/talker/blob/dev/docs/assets/talker_bloc_logger/preview.png?raw=true)### Getting started
Follow these steps to use this package### Add dependency
```yaml
dependencies:
talker_bloc_logger: ^4.4.1
```### Usage
Just set **TalkerBlocObserver** as Bloc.observer field and it will work```dart
import 'package:talker_bloc_observer/talker_bloc_observer.dart';Bloc.observer = TalkerBlocObserver();
```## Customization
To provide hight usage exp here are a lot of settings and customization fields in TalkerBlocLoggerSettings. You can setup all wat you want. For example:
### Off/on events, transitions, changes, creation, close
You can toggle all bloc event types printing
```dart
Bloc.observer = TalkerBlocObserver(
settings: TalkerBlocLoggerSettings(
enabled: true,
printChanges: true,
printClosings: true,
printCreations: true,
printEvents: true,
printTransitions: true,
),
);
```### Full/truncated state and event data
You can choose to have the logs of events and states in the BLoC displayed in the console in either full or truncated form
```dart
Bloc.observer = TalkerBlocObserver(
settings: TalkerBlocLoggerSettings(
printEventFullData: false,
printStateFullData: false,
),
);
```### Filter bloc logs
You can output logs to the console for specific events and states only, using a filter
```dart
Bloc.observer = TalkerBlocObserver(
settings: TalkerBlocLoggerSettings(
// If you want log only AuthBloc transitions
transitionFilter: (bloc, transition) =>
bloc.runtimeType.toString() == 'AuthBloc',
// If you want log only AuthBloc events
eventFilter: (bloc, event) => bloc.runtimeType.toString() == 'AuthBloc',
),
);
```## Using with Talker!
You can add your talker instance for TalkerBlocLogger if your Appication already uses Talker.In this case, all logs and errors will fall into your unified tracking system
```dart
import 'package:talker_bloc_observer/talker_bloc_observer.dart';
import 'package:talker/talker.dart';final talker = Talker();
Bloc.observer = TalkerBlocObserver(talker: talker);
```## Talker Riverpod Logger
Lightweight, simple and pretty solution for logging if your app use [Riverpod](https://pub.dev/packages/riverpod) as state management
This is how the logs of your Riverpod's event calling and state emits will look in the console
![](https://github.com/Frezyx/talker/blob/dev/docs/assets/talker_riverpod_logger/preview.png?raw=true)### Getting started
Follow these steps to use this package### Add dependency
```yaml
dependencies:
talker_riverpod_logger: ^4.4.1
```### Usage
Just pass **TalkerRiverpodObserver** to either `ProviderScope` or `ProviderContainer` and it will work```dart
import 'package:talker_riverpod_observer/talker_riverpod_observer.dart';runApp(
ProviderScope(
observers: [
TalkerRiverpodObserver(),
],
child: MyApp(),
)
);
```or
```dart
import 'package:talker_riverpod_observer/talker_riverpod_observer.dart';final container = ProviderContainer(
observers: [
TalkerRiverpodObserver(),
],
);
```## Customization
To provide hight usage exp here are a lot of settings and customization fields in TalkerRiverpodLoggerSettings. You can setup all wat you want. For example:
### Off/on events, add, update, dispose, fail
You can toggle all riverpod event types printing
```dart
TalkerRiverpodObserver(
settings: TalkerRiverpodLoggerSettings(
enabled: true,
printProviderAdded: true,
printProviderUpdated: true,
printProviderDisposed: true,
printProviderFailed: true,
),
)
```### Full/truncated state data
You can choose to have the logs of states in the Riverpod displayed in the console in either full or truncated form
```dart
TalkerRiverpodObserver(
settings: TalkerRiverpodLoggerSettings(
printStateFullData: false,
),
)
```### Filter Riverpod logs
You can output logs to the console for specific events only, using a filter
```dart
TalkerRiverpodObserver(
settings: TalkerRiverpodLoggerSettings(
// If you want log only AuthProvider events
eventFilter: (provider) => provider.runtimeType == 'AuthProvider',
),
)
```## Using with Talker!
You can add your talker instance for TalkerRiverpodLogger if your Appication already uses Talker.In this case, all logs and errors will fall into your unified tracking system
```dart
import 'package:talker_riverpod_observer/talker_riverpod_observer.dart';
import 'package:talker/talker.dart';final talker = Talker();
runApp(
ProviderScope(
observers: [

final container = ProviderContainer(
observers: [
TalkerRiverpodObserver(
talker: talker,
),
],
);
```## Crashlytics integration
If you add CrashlyticsTalkerObserver to your application, you will receive notifications about all application errors in the Crashlytics dashboard.
Additionally, you can **configure it to send only specific errors** to Crashlytics from within TalkerObserver.
```dart
import 'package:firebase_crashlytics/firebase_crashlytics.dart';
import 'package:talker/talker.dart';class CrashlyticsTalkerObserver extends TalkerObserver {
CrashlyticsTalkerObserver();@override
void onError(err) {
FirebaseCrashlytics.instance.recordError(
err.error,
err.stackTrace,
reason: err.message,
);
}@override
void onException(err) {
FirebaseCrashlytics.instance.recordError(
err.exception,
err.stackTrace,
reason: err.message,
);
}
}final crashlyticsTalkerObserver = CrashlyticsTalkerObserver();
final talker = Talker(observer: crashlyticsTalkerObserver);
