Getting Started

  1. Depend on it by adding this to your pubspec.yaml file: background_app_bar: ^1.0.0

  2. Import it: import 'package:background_app_bar/background_app_bar.dart'

  3. Replace your current FlexibleSpaceBar (In the AppBar or SliverAppBar) to BackgroundFlexibleSpaceBar.

new SliverAppBar(

    floating: false,
    pinned: true,
    snap: false,
    elevation: 0.0,
    backgroundColor: Colors.transparent,
    flexibleSpace: new BackgroundFlexibleSpaceBar(
        title: new Text( widget.title ),
        centerTitle: false,
        titlePadding: const EdgeInsets.only(left: 20.0, bottom: 20.0),
        background: new ClipRect(
            child: new Container(
                child: new BackdropFilter(
                    filter: new ImageFilter.blur(sigmaX: 5.0, sigmaY: 5.0),
                    child: new Container(
