Got this Error when changing theme:

flutter: ══╡ EXCEPTION CAUGHT BY RENDERING LIBRARY ╞═════════════════════════════════════════════════════════ flutter: The following assertion was thrown during performLayout(): flutter: RenderShrinkWrappingViewport does not support returning intrinsic dimensions. flutter: Calculating the intrinsic dimensions would require instantiating every child of the viewport, which flutter: defeats the point of viewports being lazy. flutter: If you are merely trying to shrink-wrap the viewport in the main axis direction, you should be able flutter: to achieve that effect by just giving the viewport loose constraints, without needing to measure its flutter: intrinsic dimensions. flutter: flutter: User-created ancestor of the error-causing widget was: flutter: AlertDialog
