[flutter_tools] UnsupportedError at _Uri._checkWindowsPathReservedCharacters when parsing file entries with invalid characters in assets section in pubspec.yaml #141211
Description
Highly related: #140092
Repro steps (Windows host only):
- Create a new flutter project.
- In the
assetssection of your pubspec, add a file path that includes : anywhere in the path (such ashttps://website.com/file.png) - flutter run -d chrome (the crash does not happen when using -d windows).
