Answer 1

這是試圖找到的gradle代碼： https://github.com/flutter/flutter/blob/master/packages/flutter_tools/lib/src/android/gradle.dart#L37

flutter命令位於您下載的flutter SDK的bin目錄中。它添加到您的路徑是覆蓋在我們的設置文檔：https://flutter.io/setup/#get-the-flutter-sdk

可以使用參數傳遞給命令或全球使用flutter config與--gradle-dir或--android-studio-dir標誌指定gradle這個二進制文件的位置。

正如您在鏈接代碼中所看到的，我們知道如何在某些默認位置（如/Applications/Android Studio.app內部）或通過讀取路徑變量來查找gradle。我們可能可以添加更多的默認位置。

如果您認爲您的Android SDK安裝在默認位置，我們不檢查，請提交https://github.com/flutter/flutter/issues/new的錯誤，我們很樂意解決。
