show_hide_fab

A flutter package that provides easy methods to show and hide a FAB attached to a Scaffold.

Basic Usage

Simply add the ShowHideFAB to your Scaffold as the floatingActionButton parameter.

ShowHideFAB(
  shouldShow: showFab,
  animationDuration: Duration(milliseconds: 500),
  fab: FloatingActionButton(
    backgroundColor: Colors.green,
    child: Icon(Icons.add, color: Colors.white),
    onPressed: () {},
  ),
),

Example

This code demonstrates showing and hiding the fab using a button.

class MyHomePage extends StatefulWidget {
  final String title;

  MyHomePage({this.title});

  @override
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  bool show = true;

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      ),
      body: Center(
        child: RaisedButton(
          onPressed: () {
            setState(() {
              show = !show;
            });
          },
          color: Colors.green,
          child: Text(
            show ? 'HIDE FAB' : 'SHOW FAB',
            style: TextStyle(color: Colors.white),
          ),
        ),
      ),
      floatingActionButton: ShowHideFAB(
        shouldShow: show,
        animationDuration: Duration(milliseconds: 250),
        fab: FloatingActionButton(
          backgroundColor: Colors.green,
          child: Icon(Icons.add, color: Colors.white),
          onPressed: () {},
        ),
      ),
    );
  }
