# Money Field
A simple to use TextEditingController for handling money values.
## Install
### 1. Add money_field to your pubspec.yaml:
```yaml
dependencies:
money_field: ^1.0.0
```
### 2. Install it
```
flutter packages get
```
### 3. Import it:
```dart
import 'package:money_field/money_field.dart';
```
## Usage
```dart
final _moneyFieldController = MoneyFieldController();
...
TextFormField(
controller: _moneyFieldController,
keyboardType: TextInputType.number,
),
```
### Customization Options
```dart
final _moneyFieldController = MoneyFieldController(
decimalSeparator = '.',
thousandsSeparator = ',',
invalidFormatError = 'Invalid input format',
invalidLengthError = 'Length must be less than or equal to 9',
maxDigitsBeforeDecimal = 9
);
```
### Convert Input to Double
```dart
final _moneyFieldController = MoneyFieldController();
var doubleValue = _moneyFieldController.doubleValue();
```
### Field Validation
```dart
final _moneyFieldController = MoneyFieldController();
TextFormField(
controller: _moneyFieldController,
keyboardType: TextInputType.number,
validator: (_) {
return _moneyFieldController.moneyFieldValidator();
},
),
```
### Check if Input is Valid
If you'd just like to check if the input is valid, without using the validator, you can:
```dart
final _moneyFieldController = MoneyFieldController();
bool isFormatValid = _moneyFieldController.isFormatValid();
bool isLengthValid = _moneyFieldController.isLengthValid();
// Checks if format and length are valid
bool isValid = _moneyFieldController.isInputValid();
```
