I/flutter ( 6245): The constraints that applied to the RenderCustomMultiChildLayoutBox were: I/flutter ( 6245): parentData: (can use size) I/flutter ( 6245): NotificationListener ← ⋯ I/flutter ( 6245): _ExcludableScrollSemantics- ← RepaintBoundary ← CustomPaint ← RepaintBoundary ← I/flutter ( 6245): Listener ← _GestureSemantics ← I/flutter ( 6245): creator: _SingleChildViewport ← _ScrollableScope ← IgnorePointer- ← Semantics ← I/flutter ( 6245): _RenderSingleChildViewport#d8e19 NEEDS-LAYOUT NEEDS-PAINT I/flutter ( 6245): The nearest ancestor providing an unbounded height constraint is: I/flutter ( 6245): inside another render object that allows its children to pick their own size. I/flutter ( 6245): This probably means that it is a render object that tries to be as big as possible, but it was put I/flutter ( 6245): RenderCustomMultiChildLayoutBox object was given an infinite size during layout. I/flutter ( 6245): The following assertion was thrown during performLayout(): Follow me on Instagram for snippets and day-to-day programming. Size screenSize ( BuildContext context ) Ĭheckout and subscribe to my Youtube Channel. Let's start by making a file called screensize_reducers.dart and we'll add a screenSize function first with basic screenHeight and screenWidth reducers that divides the height by a number we pass in. Let's see how this would look using reducers. Have a container half the size of the screen height (blue), another container a third the size of the screenheight(yellow) and a toolbar on the right (purple), while taking into account the height of the AppBar that's added to the Scaffold. You'll also have to re-use them in different widgets. In certain layouts will require you to make some calculations on those sizes. Getting the screen size in Flutter is trivial, and not verobose (for the most part).
