In this tutorial, you will learn how to make gradient app bar in flutter ? Before start anything, In every code we need a page for contain our whole source code. So let's start…

                                  import                  "package:flutter/material.dart";                                      class                    AppBar                    extends                    StatefulWidget                  {                  @override                  _AppBarState createState() => _AppBarState(); }                                      class                    _AppBarState                    extends                    State<AppBar>                  {                  @override                  Widget build(BuildContext context) {                  return                  Scaffold(         appBar: AppBar(           title: Text("Custom Gradient AppBar"),         ),         body: Text("XXXXXXX"));   } }

We have used the

              AppBar

in our code above, just a simple one. It will show an app bar with a title. It is easy to use. It usually uses with theappBar parameter of the

              Scaffold

Now the quetion arises is it possible to convert a simple appbar in gradient appbar ??

Yes, it is possible, let's see

Here in the appbar there is simple property which is flexibleSpace. In that flexibleSpace we can use a widget. So now we simply use a

              Container

and gives a gradient layout using linear or any other gradient method.

                appBar: AppBar(       centerTitle:                  true,         title: Text(widget.title),         flexibleSpace: Container(           decoration: BoxDecoration(             gradient: LinearGradient(               begin: Alignment.topLeft,                 end: Alignment.bottomRight,                 colors: <Color>[               Colors.red,               Colors.blue             ])                    ),              ),        ),

In this above code, we use gradient method for color and that's solve our problem
