运行失败

你好，我在mac机器上下载了最新的flutter 1.10.7，xcode是10.1版本，下载代码后执行flutter run，很多报错类似于下面这样：
../sdk/flutter/packages/flutter/lib/src/rendering/viewport.dart:161:6: Error: This can't be used as metadata; metadata should be a reference to a compile-time constant variable, or a call to a constant constructor. @required ViewportOffset offset, ^ ../sdk/flutter/packages/flutter/lib/src/rendering/viewport.dart:372:6: Error: Getter not found: 'required'. @required RenderSliver child, ^^^^^^^^ ../sdk/flutter/packages/flutter/lib/src/rendering/viewport.dart:372:6: Error: This can't be used as metadata; metadata should be a reference to a compile-time constant variable, or a call to a constant constructor. @required RenderSliver child, ^ ../sdk/flutter/packages/flutter/lib/src/rendering/viewport.dart:373:6: Error: Getter not found: 'required'. @required double scrollOffset, ^^^^^^^^ ../sdk/flutter/packages/flutter/lib/src/rendering/viewport.dart:373:6: Error: This can't be used as metadata; metadata should be a reference to a compile-time constant variable, or a call to a constant constructor. @required double scrollOffset, ^
请问怎么解决？

应该是flutter的版本低了，用flutter2.0.0之后的版本试试呢
