double_back_to_close_app

A Flutter package that allows Android users to press the back-button twice to close the app.

Usage

Inside a Scaffold that wraps all your Widgets, place the DoubleBackToCloseApp passing a SnackBar:

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        body: DoubleBackToCloseApp(
          child: Home(),
          snackBar: const SnackBar(
            content: Text('Tap back again to leave'),
          ),
        ),
      ),
    );
  }
}

Motivation

I've implemented such solution when I answered this question in Stack Overflow, and since this feature seems to be implemented very often, I decided to extract it in a lightweight library.
