Flutter 在 visual studio code 啟動調試時，卡在 Running Gradle task 'assembleDebug'....... 問題
該問題由 Gradle 的Maven倉庫在國外訪問受限引起，使用阿里雲的鏡像倉庫地址替代解決
以下 3 個文件
1. Flutter SDK 目錄：flutter\packages\flutter_tools\gradle\resolve_dependencies.gradle
2. Flutter SDK 目錄：flutter\packages\flutter_tools\gradle\flutter.gradle
3. 項目：android\build.gradle
修改替換掉里面的 repositories 配置
把
google()
mavenCentral()
替換為
maven { url 'https://maven.aliyun.com/repository/google' }
maven { url 'https://maven.aliyun.com/repository/jcenter' }
maven { url 'http://maven.aliyun.com/nexus/content/groups/public' }
