Hi thanks for reporting this.

I'll need more information. Could you provide steps on how to replicate this issue?

[granoeste]

1. Define flutter_launcher_icons in pubspec.yaml

dev_dependencies:
  flutter_launcher_icons: ^0.7.0

2. Display LicensePage with the following code with onPressed of Button etc.

            showLicensePage(context: context);

showLicensePage function - material library - Dart API

I think the definition of LICENSE is a problem...

[MarkOSullivan94]

Might have been due to the year / name not being put in, I've updated it in the master branch for now and should hopefully no longer cause any issues in the next release

@MarkOSullivan94 This issue keeps happening, but not because of flutter_launcher_icons, but because of image package. At least for me that's where it broke...

[MarkOSullivan94]

@granoeste v0.7.1 has been released - let me know if this fixes your issue

@miguelcmedeiros that issue is unrelated to this one and should be fixed in v0.7.1 see these two issues which are related

I am not sure about the status of this.

I've started working on a flutter project on and off around two months ago. After noticing this week that showLicensePage generates an exception, I've disabled all packages from pubspec.yaml one at a time and found out that "flutter_launcher_icons" was responsible for the problem.

After that, I've updated the version to 0.7.3, uncommented the dependency and showLicensePage seems to still work fine.

[micsanbr]

Okay so I forgot to clean / rebuild the project properly. The issue reappears after re-introducing the dependency.

I can confirm what @micsan13br is seeing. Since we don't need flutter_launcher_icons at runtime, we just comment it out in pubspec.yaml for our builds and showLicensePage works correctly from there.
