成功生成启动程序图标，未处理的异常: FileSystemException:无法打开文件，path = 'dev_assets/news-logos.jpeg‘

Question

当我试图用"flutter_launcher_icons 0.9.2“更改应用程序图标时，我得到了这个错误。我试过指定minsdk和targetsdk的应用程序，但这不起作用，我已经做过几次颤栗酒吧了。在那之后，当我这样做的时候:颤栗酒吧运行flutter_launcher_icons:main。我知道这个错误

这是我的pubspec.yaml：

dev_dependencies:
  flutter_test:
    sdk: flutter
  flutter_launcher_icons: ^0.9.2

flutter_icons:
  android: true
  ios: true
  image_path: "dev_assets/news-logos.jpeg"
  adaptive_icon_background: "#FFFFFF"
  adaptive_icon_foreground: "dev_assets/news-logos.jpeg"

我的android/应用程序/build.gradle：

defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "com.example.news_app"
        minSdkVersion 21
        targetSdkVersion 29
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        multiDexEnabled true
    }

完全错误：

Answer 1

这似乎是窗口错误。我没有什么解决办法

1. 右键单击news-logos.jpeg并复制相对路径，然后粘贴到任何需要它的地方。
2. 将dev_assets/news-logos.jpeg更改为dev_assets\news-logos.jpeg，因为windows不使用/

Answer 2

目前图标只支持PNG图像格式，所以在您的应用程序中可能会出现这个问题。尝试添加PNG图像。

Answer 3

读取错误时，文件的路径不正确。
