ConstraintLayout - DimensionRatio on Android Platform issue #25427

Open abelaegerter opened 4 days ago

abelaegerter commented 4 days ago

Description

Recentrly testing write custom handlers to make a new controls, an aspect ratio view to be specific. On Android the best aproach (or at least i think) is to use a ConstraintLayout and a child with the layout_constraintDimensionRatio. Everithing goes well, handlers are registred, detect diferent platforms, etc. The problem is that on Android, if the view has not a defined WidthRequest (any number > 0) the child is not rendered as espected.

@abelaegerter discussions might be a better place to start with this one.

Because this is custom layouts it probably won't get prioritized to review for a bit
