android - 有没有办法在颤动中使用 .svg 作为应用程序图标？

问题描述

我正在使用flutter_launcher_icons包在颤振应用程序中设置默认应用程序图标（特别适用于android）。现在，我必须使用svg文件作为图标，因为png图标在通知栏中的深色主题 android 版本中显示不正确。但它显示了一些错误NoDecoderForImageFormatException。

pubspec.yaml 文件配置：


flutter_icons:
  #  image_path: "assets/images/icon-128x128.png"
  android: "launcher_icon"
  ios: true
  image_path: "assets/images/logo.svg"

这是flutter pub run flutter_launcher_icons:main命令的输出。


pub run flutter_launcher_icons:main

解决方案

The package flutter_launcher_icons only uses PNG images to create all the different sizes of logos (hdpi, mdpi, xhdpi etc...)

If you have a problem with Android, did you try to use the adaptive_icon_background and adaptive_icon_foreground attribute?
