DEMO的页面push生硬
建议使用默认的 Navigator.pushName
这么生硬的DEMO很影响Flutter在开发者技术选型时的判断

hi there, thanks for sharing this knowledge and techniques.
i wanted to suggest that you add a tutorial regarding the exact steps to take for making a successful build.
there are many problems associated with the current version:

1. updating packages in pubspec.yaml results in breaking changes that prevent the app from compiling. so I think either it needs to be updated or a warning needs to be

login_challenge.dart
Emulator display overflow image when text field get focus because keyboard shows.
Wrap with SingleChildScrollView seems fix the problem

Thanks
