The only two widgets that throw this error are
UnconstrainedBox, the former is obviously the most common.
The problem is not actually the fault of the Flex itself, rather the constraints given by its parent. In order to solve this issue the main axis constraint needs to either be unbounded i.e. have a maximum main axis size of
double.infinity or have a
The simplest way to ignore overflow is to use
Flex instead, and set the clip:
Flex( direction: Axis.horizontal, clipBehavior: Clip.none, children: [ Some(), Long(), Widgets(), ], )
Or using OverflowBox:
OverflowBox( maxWidth: double.infinity, child: Row(children: [ Some(), Long(), Widgets(), ]), )
I’ve seen some people use
Wrap to achieve a similar result, I highly discourage that because the fact that
Wrap doesn’t check for overflow is probably an oversight and may change in the future.
