_x000D_ _x000D_ I am a beginner in Flutter and Dart, and I am working on designing a custom navigation bar. What I would like to know is how can I use flutter to transform a rectangle into this kind of shape? Any help or tutorials on custom drawn widgets are much appreciated!

_x000D_ ClipPath can be the solution for you and you can create custom clippers like this : class MyClipper extends CustomClipper { @override Path getClip(Size size) { Path myPath = Path(); myPath.lineTo(0.0, size.height); myPath.quadraticBezierTo( size.width / 4, size.height / 1.2, size.width / 2, size.height / 1.2 ); myPath.quadraticBezierTo( size.width - (size.width / 4), size.height / 1.2, size.width, size.height); myPath.lineTo(size.width, 0.0); return myPath; } @override bool shouldReclip(CustomClipper oldClipper) { return false; } } I posted my whole code in the follow, you can play with it and convert to what you need : import 'package:flutter/material.dart'; void main() { runApp(MyApp()); } class MyApp extends StatefulWidget { @override _MyAppState createState() => _MyAppState(); } class _MyAppState extends State { @override Widget build(BuildContext context) { return MaterialApp( home: Scaffold( body: Container( child: Center( child: ClipPath( clipper: MyClipper(), child: Container( height: 200, width: 300, color: Colors.black26, ), )), ), ), ); } } class MyClipper extends CustomClipper { @override Path getClip(Size size) { Path myPath = Path(); myPath.lineTo(0.0, size.height); myPath.quadraticBezierTo( size.width / 4, size.height / 1.2, size.width / 2, size.height / 1.2 ); myPath.quadraticBezierTo( size.width - (size.width / 4), size.height / 1.2, size.width, size.height); myPath.lineTo(size.width, 0.0); return myPath; } @override bool shouldReclip(CustomClipper oldClipper) { return false; } }
