`material_3_demo` experimental renderflex overflows

[fredgrott]

Getting renderFlex overflow errors on small screens.

mainAxisSize: MainAxisSize.min not applied on Rows and Text items not wrapped via Flexible widget. Affected classes are:

ComponentDecoration SwitchRow Radios FloatingActionButtons CheckboxRow

Once those things are added the renderflex overflows no longer occur.

Hi! I think mainAxisSize: MainAxisSize.min might affect the layout of the components, right? I'm trying to reproduce the issue. Which device do you use to test the app? Thanks!

I can reproduce this on my monitor (probably 22.9").

Steps to reproduce

1. Run the experimental demo https://github.com/flutter/samples/tree/main/experimental/material_3_demo
2. Double tap the window to maximize

The relevant error-causing widget was: Row Row:file:///Users/tahatesser/Projects/samples/experimental/material_3_demo/lib /component_screen.dart:2211:13 To inspect this widget in Flutter DevTools, visit: http://127.0.0.1:9100/#/inspector?uri=http%3A%2F%2F127.0.0.1%3A49805%2FeoByzN1Sd qU%3D%2F&inspectorRef=inspector-0 The overflowing RenderFlex has an orientation of Axis.horizontal. The edge of the RenderFlex that is overflowing has been marked in the rendering with a yellow and black striped pattern. This is usually caused by the contents being too big for the RenderFlex. Consider applying a flex factor (e.g. using an Expanded widget) to force the children of the RenderFlex to fit within the available space instead of being sized to their natural size. This is considered an error condition because it indicates that there is content that cannot be seen. If the content is legitimately bigger than the available space, consider clipping it with a ClipRect widget before putting it in the flex, or using a scrollable container rather than a Flex, like a ListView.

I'm closing this issue as experimental demo 3 has been removed in the samples repo.
