Can't scroll to bottom if maxHeight > available height

[magnuswikhog]

Describe the bug I have a SlidingUpPanel containing a SingleChildScrollView, using panelBuilder and its provided scrollcontroller. I noticed that I can't scroll to the bottom of the contents if I set maxHeight of the panel to anything bigger than the available height (i.e. typically the screen height - AppBar height).

To Reproduce

        SlidingUpPanel(
          maxHeight: 2000,
          minHeight: 40,
          panelBuilder: (scrollController){
            return SingleChildScrollView(
              controller: scrollController,
              child: Column(
                children: List.generate(200, (index) => Text('index: $index'))
              ),
            );
          }
        );

Expected behavior To be able to scroll down to see "index: 199". Instead I can only scroll to "index: 116" (on my particular phone, results may vary).

Screenshots

Additional context Appears to be solvable by wrapping the panel in a LayoutBuilder, and providing the constrained maxHeight from the builder to the panel:

        LayoutBuilder(
          builder: (context, constraints) {
            return SlidingUpPanel(
              maxHeight: constraints.maxHeight,
              minHeight: 40,
              panelBuilder: (scrollController){
                return SingleChildScrollView(
                  controller: scrollController,
                  child: Column(
                    children: List.generate(200, (index) => Text('index: $index'))
                  ),
                );
              }
            );
          }
        );
