Flutter導入別人項目報錯

如果報如下類似錯誤

Warning! This package referenced a Flutter repository via the .packages file that is no longer available. The repository from which the 'flutter' tool is currently executing will be used instead.

running Flutter tool: /Users/xxx/Documents/flutter/flutter

previous reference : /Users/xxx/Documents/xxxx/flutter

則在AdroidStuido中terminal

用如下命令

flutter packages upgrade

即可。

如果遇到還有其它文件缺少的庫，就找到這個yaml文件，點擊右邊packages get下載下庫就可以了

2.還有一種代碼報錯解決方案

//        FocusScope.of(context).reparentIfNeeded(node);
        FocusScopeNode _node = node;
        FocusAttachment _nodeAttachment = _node.attach(context);
        _nodeAttachment.reparent();
