Issue Description

A rendering exception is occurring in the AlertDialog component due to improper layout sizing of a RenderPhysicalShape widget. The widget attempts to paint before its dimensions are properly calculated, causing a layout failure.

Error Message:
error_log.txt

RenderBox was not laid out: RenderPhysicalShape#f9904 relayoutBoundary=up2
Failed assertion: line 2164 pos 12: 'hasSize'

This occurs when Flutter tries to paint a widget that hasn't been adequately laid out yet. Looking at the error message, it's happening in an AlertDialog in your import_playlist_dialog.dart file in Android Pixel4.

Additional Notes

This fix addresses the layout assertion error that was preventing the AlertDialog from rendering properly. The changes ensure that all widgets in the component tree have proper size constraints before the paint phase.
