You can use FlatButton within an AppBar‘s actions list: appBar: AppBar( title: Text(“Test Screen”), actions: <Widget>[ FlatButton( textColor: Colors.white, onPressed: () {}, child: Text(“Save”), shape: CircleBorder(side: BorderSide(color: Colors.transparent)), ), ], ), onPressed must be defined or the button will appear disabled. Also note that by default the shape of the button will create a filled … Read more
Maybe something like this AppBar( bottom: PreferredSize( preferredSize: const Size.fromHeight(4.0)), child: Container( color: Colors.orange, height: 4.0, ), )
I tried the method SystemChrome.setSystemUIOverlayStyle(), as far as I tested (Flutter SDK v1.9.1+hotfix.2, running on iOS 12.1) it works perfect for Android. But for iOS, e.g. if your first screen FirstScreen() doesn’t have an AppBar, but the second SecondScreen() does, then at launch the method does set the color in FirstScreen(). However, after navigating back … Read more
import ‘package:flutter/material.dart’; class CustomAppBar extends StatefulWidget implements PreferredSizeWidget { CustomAppBar({Key key}) : preferredSize = Size.fromHeight(kToolbarHeight), super(key: key); @override final Size preferredSize; // default is 56.0 @override _CustomAppBarState createState() => _CustomAppBarState(); } class _CustomAppBarState extends State<CustomAppBar>{ @override Widget build(BuildContext context) { return AppBar( title: Text(“Sample App Bar”) ); } } Hopefully this helps
This should work flawlessly: return Scaffold( appBar: AppBar( title: Text(widget.title), flexibleSpace: Container( decoration: const BoxDecoration( gradient: LinearGradient( begin: Alignment.topCenter, end: Alignment.bottomCenter, colors: <Color>[Colors.black, Colors.blue]), ), ), ), );
You can change the color of the TabBar by changing the Theme primaryColor like that: return MaterialApp( theme: ThemeData( brightness: Brightness.light, // add tabBarTheme tabBarTheme: const TabBarTheme( labelColor: Colors.pink[800], labelStyle: TextStyle(color: Colors.pink[800]), // color for text indicator: UnderlineTabIndicator( // color for indicator (underline) borderSide: BorderSide(color: ConstColor.primary))), primaryColor: Colors.pink[800], // outdated and has no effect to … Read more
This is another way of going about it. By doing this you can customize this appbar to the way you want. That way, if you continue with that style, you don’t have to recreate it on every page. You create it once and call on it within any widget. Class import ‘package:flutter/material.dart’; class BaseAppBar extends … Read more
Please Note: This question gathered a good amount of feedback, and some people below have made great points or fixes. Therefore, while I’ll keep the code here (and possibly update it), I’ve also created a WpfAppBar project on github. Feel free to send pull requests. That same project also builds to a WpfAppBar nuget package … Read more
This is not an ideal way, I think, but it will work. Firstly declare the AppBar widget that you will use in your Scaffold. Widget demoPage() { AppBar appBar = AppBar( title: Text(‘Demo’), ); return Scaffold( appBar: appBar, body: /* page body */, ); } Now you can get the height of your appBar using … Read more
Looking at the AppBar constructor, there’s an elevation property that can be used to set the height of the app bar and hence the amount of shadow cast. Setting this to zero removes the drop shadow: @override Widget build(BuildContext context) { return Scaffold( appBar: AppBar( title: const Text(‘My App Title’), elevation: 0, ), body: const … Read more
