im getting this error when building discovery

══╡ EXCEPTION CAUGHT BY FLUTTER ╞═══════════════════════════════════════════════════════════════════
The following _Exception was thrown while applying parent data.
:
Exception: Incorrect use of ParentDataWidget.
The ParentDataWidget Expanded(flex: 2) wants to apply ParentData of type FlexParentData to a
RenderObject, which has been set up to accept ParentData of incompatible type WrapParentData.
Usually, this means that the Expanded widget has the wrong ancestor RenderObjectWidget. Typically,
Expanded widgets are placed directly inside Flex widgets.
The offending Expanded is currently placed inside a Wrap widget.
The ownership chain for the RenderObject that received the incompatible parent data was:
  Column ← Expanded ← _CampaignFundsDetail ← Wrap ← SizedBox ← Column ← Padding ← DecoratedBox ←
Container ← _CurrentCampaignDetails ← ⋯
