Background Image for Scaffold

Ankur Prakash picture Ankur Prakash · Jan 17, 2019 · Viewed 19.1k times · Source

I want to set the image as the background color for Scaffold. When setting an AppBar and bottom bar, using the decoration of the Container as the body of the scaffold doesn't cover the complete screen.

I want to show background for full screen. Below is my Scaffold code:

Scaffold(
      backgroundColor: Image.asset('images/background.png').color,
      body: Container(
        decoration: defaultAppBoxDecoration(),
      ),
      appBar: AppBar(
        elevation: 0.0,
        backgroundColor: Colors.transparent,
        title: Text('Title here', style: TextStyle(color: Colors.teal),),
        leading: IconButton(
          icon: Image.asset('images/star.png'),
          onPressed: () {},
        ),
        actions: <Widget>[
          IconButton(icon: Image.asset('images/star.png')),
                  //  IconButton(icon: Image.asset('images/grid.png')),

        ],
      ),
      floatingActionButtonLocation: FloatingActionButtonLocation.centerDocked,
      floatingActionButton: FloatingActionButton(
        child:           IconButton(icon: Image.asset('images/star.png')),
      ),
      bottomNavigationBar: Container(
        padding: EdgeInsets.only(left: 4.0, right: 4.0),
        height: 44.0 + MediaQuery.of(context).padding.bottom,
        child: Row(
          mainAxisAlignment: MainAxisAlignment.spaceBetween,
          children: <Widget>[
                      IconButton(icon: Image.asset('images/star.png')),
          IconButton(icon: Image.asset('images/star.png')),

          ],
        ),
      ),
    );

Please refer to the image

Try using Stack check the following sample:

  @override
    Widget build(BuildContext context) {
      return Stack(
        children: <Widget>[
          Image.asset(
            "resources/background.png",
            height: MediaQuery.of(context).size.height,
            width: MediaQuery.of(context).size.width,
            fit: BoxFit.cover,
          ),
          Scaffold(
              backgroundColor: Colors.transparent,
              appBar: AppBar(
                backgroundColor: Colors.transparent,
                elevation: 0.0,
              ),
              bottomNavigationBar: Container(
                padding: EdgeInsets.only(left: 4.0, right: 4.0),
                height: 44.0 + MediaQuery.of(context).padding.bottom,
                child: Row(
                  mainAxisAlignment: MainAxisAlignment.spaceBetween,
                  children: <Widget>[
                    IconButton(icon: Icon(Icons.star)),
                    IconButton(icon: Icon(Icons.star)),
                  ],
                ),
              ),
              body: Text("Hello world"))
        ],
      );
    }
