Unimplemented handling of missing static target

[JaeHo Song]

Please give me some hint how I can solve this issue.

This issue only happens on hot restart (NOT hot reload).

_CompileTimeError was thrown building ... Unimplemented handling of missing static target

I am using GetX controller and the following "flutter doctor -v"

```

$ flutter doctor -v

It was okay yesterday, and suddenly this issue occurred.

I am looking for advices.

Thank you.

I fixed this issue by adjusting import path.

One widget is importing source file directly like `import ../../packages/abc/lib/abc.dart`, while other widget is importing like `import package:abc/abc.dart`.
