Change title bar color in flutter windows desktop
In Flutter for Windows desktop, changing the title bar color involves utilizing platform-specific code and interacting with the underlying Windows API. Here's an outline of the steps you can follow to change the title bar color in a Flutter Windows desktop application:
Create a new Flutter project: Use the
flutter create
command to create a new Flutter project if you haven't already.Add Windows-specific dependencies: Open the
pubspec.yaml
file in your Flutter project and add thewin32
package as a dependency. This package provides access to the Windows API.yamldependencies:
flutter:
sdk: flutter
win32: ^2.0.3
Create a Windows-specific entry point: In the
lib
directory of your Flutter project, create a new file namedmain_windows.dart
. This file will serve as the entry point for the Windows desktop application.Configure the entry point: In the
main_windows.dart
file, add the necessary imports and define the main function as follows:dartimport 'dart:ffi';
import 'package:win32/win32.dart';
void main() {
final hInstance = GetModuleHandle(nullptr);
// Configure the title bar color here
runApp(MyApp());
}
Configure the title bar color: Inside the main function, you can use Windows API functions to configure the title bar color. For example, you can use
DwmSetColorizationParameters
to set the colorization parameters. Refer to the Windows API documentation for more information on manipulating the title bar color.Run the Windows desktop application: Open the
main.dart
file in your Flutter project and update themain
function to run the Windows-specific entry point when the application is being executed on the Windows desktop platform.dartimport 'package:flutter/foundation.dart';
import 'package:flutter/material.dart';
import 'main_windows.dart' // Import the Windows-specific entry point
void main() {
if (kIsWeb) {
// Run the regular Flutter app for other platforms
runApp(MyApp());
} else {
// Run the Windows-specific entry point for Windows desktop
mainWindows();
}
}
Build and run the Windows desktop application: Use the
flutter run
command to build and run the Flutter application on the Windows desktop. Make sure to specify the Windows desktop target platform using the--target-platform
flag.bashflutter run -d windows --target-platform=windows
This command will build and run the application specifically for the Windows desktop platform.
Remember to adjust the code and colorization parameters according to your specific requirements for changing the title bar color.
Please note that modifying the title bar color involves working with the Windows API, which is platform-specific. These changes will only affect the appearance of the application when it is run on the Windows desktop platform. The appearance on other platforms will remain unaffected.
