Flutter Round Bottom AppBar

We attach a curve ClipPath at the bottom of AppBar to make it a part of the AppBar for the look and feel.

class HomePage extends StatefulWidget {
  _HomePageState createState() => _HomePageState();

class _HomePageState extends State<HomePage> {
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Center(child: Text('Round AppBar')),
        backgroundColor: Colors.lightGreen,
        elevation: 0,
        actions: [Icon(Icons.dehaze_sharp)],
      body: SafeArea(
          child: Column(
        children: [
            clipper: RoundShape(),
            child: Container(
              height: 40,
              color: Colors.lightGreen,
            child: Text('Body'),

class RoundShape extends CustomClipper<Path> {
  getClip(Size size) {
    double height = size.height;
    double width = size.width;
    double curveHeight = size.height / 2;

    var p = Path();
    p.lineTo(0, height - curveHeight);
    p.quadraticBezierTo(width / 2, height, width, height - curveHeight);
    p.lineTo(width, 0);

    return p;

  bool shouldReclip(CustomClipper oldClipper) => true;
