Flutter 3.0.5 does not compile on file_picker 5.2.8

[micaelcid]

Currently, we're using Flutter 3.0.5 and as soon as we updated file_picker to 5.2.8, we started getting the following exception while compiling tests or compiling the app itself:

.pub-cache/hosted/pub.dartlang.org/file_picker-5.2.8/lib/src/platform_file.dart:53:9: Error: Type 'Uint8List' not found.
  final Uint8List? bytes;
        ^^^^^^^^^
.pub-cache/hosted/pub.dartlang.org/file_picker-5.2.8/lib/src/platform_file.dart:53:9: Error: 'Uint8List' isn't a type.
  final Uint8List? bytes;

After I manually downgraded this package back to 5.2.7, the compilation error disappeared.

By taking a glance over the change logs, I couldn't find what could cause this issue. Was this problem expected?

The issue is related to removed import here 9d1d9ef#diff-38d8f870fecf77b1946a59ac5ed87e3eac24c8a86dc31ec3fd8970896cf8c016L2

Thanks for identifying this up @miguelslemos!

I'm currently using file_picker: '>=5.2.5 <5.2.8' as a workaround until the problem is resolved.

Thank you @miguelslemos for identifying the problematic commit. Turns out, that blindly following the Linter's recommendations, can be dangerous. Sorry for the inconvenience. Will be fixed with file_picker 5.2.9.

That's interesting, I checked package:flutter/foundation.dart exports and it does export Uint8List from the file src/foundation/serialization.dart as:

export 'dart:typed_data' show ByteData, Endian, Float32List, Float64List, Int32List, Int64List, Uint8List;

weird bug it seems.
