## [Changelog](https://github.com/VarunS2002/Dart-interactive_print/blob/main/interactive_print/CHANGELOG.md)

## Usage

```yaml

dependencies:

  interactive_print: ^1.0.0

```

A simple usage example:

```dart

import 'package:interactive_print/interactive_print.dart';

void main() {

  write('Hello');

  writeln('There');

  write('General Kenobi');

  writeln('.');

}

```

## Objective of this package

The `print()` function in Dart always adds a newline to the end, so you cannot print character by character. This is

particularly useful if you want to have a delay between printing characters or if you want to construct a line

dynamically using characters at runtime. Dart has 2 supported platforms namely Native and Web. On Native, you can

use `stdout.write()` to print without a newline, however this breaks support for Web as this function is not supported.

Web also doesn't have any method to print without a newline but this behaviour can be simulated

like [this](https://stackoverflow.com/a/41817778/13978447). This Dart library provides its own `write()` and `writeln()`

function which will dynamically use `stdout.write()` or the `console.log()` trick based on the platform you are running

on. More discussion [here](https://github.com/dart-lang/sdk/issues/46383).

## Note

- May not work correctly if you run your application in debug mode.

- If you face any issue or have suggestions then feel free to open an issue on GitHub.
