Flutter 啟動器圖標命令拋出錯誤

Question

我的 flutter 應用程序中有以下配置，

但是當我嘗試更新我的應用程序的啟動器圖標時出現以下錯誤。

 Successfully generated launcher icons
Unhandled exception:
FormatException: Invalid number (at character 1)

^

#0      int._handleFormatError (dart:core-patch/integers_patch.dart:129:7)
#1      int.parse (dart:core-patch/integers_patch.dart:55:14)

#7      _RawReceivePortImpl._handleMessage (dart:isolate-patch/isolate_patch.dart:192:12)

請告知如何解決這個問題？

試試下面的代碼希望它對你有幫助。 在您的build.gradle文件project_name/android/app/build.gradle中進行一些更改

編譯 SDK

compileSdkVersion 31

最小 SDK 和目標 SDK

    minSdkVersion 23
    targetSdkVersion 30
    versionCode flutterVersionCode.toInteger()
    versionName flutterVersionName

然后嘗試以下命令：

flutter pub run flutter_launcher_icons:main
