我的目的是使用 OneSignal 向手機發送通知。我已將錯誤和上述檔案的內容放在上面。
作為指南，我在這里使用它：https ://dev.to/lordlamee/implementing-push-notifications-with-flutter-and-onesignal-part-1-3690 。我在這里做了同樣的程式。
問題是什么？我該如何解決？

uj5u.com熱心網友回復：
轉到專案的根路徑/android/app/build.gradle，然后在android -> defaultConfig塊內設定minSdkVersion to 19/21如下代碼。
defaultConfig {
applicationId "com.*****.*****"
minSdkVersion 21
targetSdkVersion 30
versionCode flutterVersionCode.toInteger()
versionName flutterVersionName
multiDexEnabled true
}
重新運行專案。我認為這將解決您的問題。
