How To Implement Flutter Appbar Transparent

In this post, I will be implementing Flutter appbar transparent using an easy Flutter code example. A detailed step by step explanation will also be provided on how to make Flutter appbar transparent means replace the background color of Flutter appbar with transparent. Everything will be explained properly so you can have a clear practical idea on how to implement Flutter appbar transparent in your Flutter apps.

What is Flutter Appbar Transparent?

Flutter appbar transparent is actually removing the background color of the Flutter appbar. In this post, we will first see what the default Flutter appbar background color is and then how to make Flutter appbar transparent using proper Flutter code. So let’s get right into the implementation phase.

Default Flutter Appbar Background Color

In order to see the default Flutter appbar background color, we have to define a simple Flutter appbar. See the below code:

appBar: AppBar()

You can see that the default Flutter appbar background color is blue. Let’s now see how to make Flutter appbar transparent.

Implementing Flutter Appbar Transparent(All Steps)

Now to make the Flutter appbar transparent, we have to use the background color constructor of the Flutter appbar and pass Colors.transparent. See the below code:

 appBar: AppBar(
      backgroundColor: Colors.transparent,
    )

Above image shows that the default color is removed but still there is some dark color that is covering the Flutter appbar area. Flutter appbar is elevated. This is the reason that the Flutter appbar transparent is not completely implemented yet.

To remove the elevation of the Flutter appbar. We have to use the elevation constructor of the Flutter appbar widget class and make it 0 to remove elevation. See the below code:

appBar: AppBar(
      elevation: 0,
      backgroundColor: Colors.transparent,
      centerTitle: true,
      title: Text(
        'Flutter Appbar transparent',
        style: TextStyle(color: Colors.blue, fontWeight: FontWeight.w700),
      ),
    )

In the above image, you can see that the Flutter appbar transparent is now completely implemented. I also have used a Flutter text widget with some Text style using the title constructor and made it center to demonstrate that the Flutter appbar is still there but with transparent background color.

Now you have a detailed practical knowledge of how to implement Flutter appbar transparent. I would love to answer your questions regarding Flutter appbar transparent background color, if you have any. The complete source code for the above Flutter appbar transparent implementation is given in the next section.

Flutter Appbar Transparent Source Code

import 'package:flutter/material.dart';
void main() {
  runApp(const MyApp());
}
class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      home: Homepage(),
    );
  }
}
class Homepage extends StatefulWidget {
  @override
  State<Homepage> createState() => _HomepageState();
}
class _HomepageState extends State<Homepage> {
  @override
  Widget build(BuildContext context) {
    return SafeArea(
        child: Scaffold(
            appBar: AppBar(
      elevation: 0,
      backgroundColor: Colors.transparent,
      centerTitle: true,
      title: Text(
        'Flutter Appbar transparent',
        style: TextStyle(color: Colors.blue, fontWeight: FontWeight.w700),
      ),
    )));
  }
}
