I think it's because of the upgraded flutter version. 1.10.5 works for me.

[ThuAbLKA]

@bd16s is right. The latest flutter version has some breaking changes.

[miquelbeltran]

If anyone wants to provide a fix, we will be happy to merge it.

[imdatceleste]

Changing flutter_platform_widgets-version to ^0.32.4 in pubspec.yaml resolves this issue because the developers of flutter_platform_widgets have fixed that already.

After that, you need to flutter packages upgrade...

Try clicking on the link mentioned in the error "package:flutter/src/cupertino/page_scaffold.dart" or the other one mentioned in the error which would be a hyperlink and change 'fullObstruction' to 'shouldFullyObstruct'. I did it today and it works.
