═╡ EXCEPTION CAUGHT BY RENDERING LIBRARY ╞═════════════════════════════════════════════════════════ The following assertion was thrown during layout: A RenderFlex overflowed by 29 pixels on the bottom.

The relevant error-causing widget was: BottomNavigationBar file:***

To inspect this widget in Flutter DevTools, visit: http://127.0.0.1:54097/#/inspector?uri=***

The overflowing RenderFlex has an orientation of Axis.vertical. 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 reproduced the overflow with the lib.zip from #1

[mrripp3r]

Anyone got a work around yet?

I don't see this as a critical issue since it is not visible in production, but this is fixed in 2ad75d4f6f3f92b33ded418dc5c85f671ac94ed6

Overflow warnings do still occur (tested on iOS Simulator).

I solved this problem by adding the

MediaQuery.of(context).padding.bottom

with the height value of 0 on iPhone 8.

~/example/lib/main.dart

[Before]

...
          return SizedBox(
            height: kBottomNavigationBarHeight - kBottomNavigationBarHeight * value,
...

[After]

...
          return SizedBox(
            height: (kBottomNavigationBarHeight + MediaQuery.of(context).padding.bottom) -
                (kBottomNavigationBarHeight + MediaQuery.of(context).padding.bottom) * value,
...
