android - Replacing app launcher icon in flutter with new icon

问题描述

I was looking for changing the app icon of my current app. I cane around the package name flutter_launcher_icons.

I also found I can do by putting an image in mipmap-xxxhdpi in android/app/res folder. And it works.

So my question is why we need additional package(flutter_launcher_icons) for this.

解决方案

当您使用该包flutter_launcher_icons时，它会自动为应用程序生成不同的图标大小，这比仅将图像mipmap-xxxhdpi放入android/app/res.

例如，如果您添加flutter_launcher_icons到pubspec.yaml：

dev_dependencies: 
  flutter_launcher_icons: "^0.7.3"

flutter_icons:
  android: "launcher_icon" 
  ios: true
  image_path: "assets/icon/icon.png"

然后执行以下命令：

flutter pub get
flutter pub run flutter_launcher_icons:main

它将在res文件夹中为android和Assets.xcassetsios生成不同大小的所有图标。
