flutter package 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.
