1.執行報錯
第一次執行 會卡在 Resovle ...中很長時間，然後就會報錯

重點在於
ProcessException: Process "C:\Codes\kakaCode\Android\flutter_app\android\gradlew.bat" exited abnormally:
原因：
flutter 需要梯子在jcenter和google庫裡下載依賴，但是又因為有厚厚的牆訪問不到，她就會在哪裡憋著不動。
解決方法：
1.需要再你app 裡的build.gradle 加 阿里雲的映象
2.需要在你flutter sdk 的 如下路徑 下的 flutter.gradle 也同樣新增映象。
E:\MspSoftwares\flutter\packages\flutter_tools\gradle 新增的內容： 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'}
此問題這兩步，可以得到解決！
如果還有其他問題，還會更新。
