AppWidget support - Problem loading Widget

[KLT1003]

• I have searched existing issues and confirmed this is not a duplicate

Issues and steps to reproduce

I tried to build an AppWidget according to https://developer.android.com/guide/topics/appwidgets with a FlexBoxLayout as the widgets main layout. Just put some simple Textview with fixed width/height (e.g. 80dp) as inner elements for testing purposes. As soon as I try to create the widget I get the appropriate calls (onReceive, onEnabled, onUpdate, etc.) but the Widget shows "Problem loading widget".
Logcat does not show any details to the cause (normally I would expect some layout inflating issues in the logcat).
Does flexbox-layout support AppWidgets?

Expected behavior

Flexbox layout should work within an AppWidget.

Version of the flexbox library

2.0.1

No it's not supported at this moment.

As far as I concern, it's not supported to use layouts or views from non-Android framework libraries at this moment.

Unfortunate and also understandable that it's not a priority, but for clarification the widgets are native Android features and not a non-Android framework library.
