Scroll through Flutter Bottom Sheet

Question

I'm using a Flutter modal bottom sheet to display some options for the user to select. I have a Column with a list of ListTiles as the content of the bottom sheet.

My problem is that if I have more than 6 ListTiles, some are cut off and not displayed.

Is there a way to make the bottom Sheet scrollable?

Answer 1

Just change your Column into a ListView, like so:

return ListView(
  children: <Widget>[
    ...
  ]
);

What if I don't want the content of the sheet to be scrolled, but the sheet itself?

If you want the user to be able to swipe up the bottom sheet to fill the screen, I'm afraid this isn't possible in the current implementation of the modular bottom sheet.

Answer 2

If you want a model bottom sheet that can be scrolled.

You can use the isScrollControlled attribute of showModalBottomSheet to achieve the effect.

If you want a persistent bottom sheet that can be scrolled.

You can use the DraggableScrollableSheet

Example:

    class HomePage extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text('DraggableScrollableSheet'),
      ),
      body: SizedBox.expand(
        child: DraggableScrollableSheet(
          builder: (BuildContext context, ScrollController scrollController) {
            return Container(
              color: Colors.blue[100],
              child: ListView.builder(
                controller: scrollController,
                itemCount: 25,
                itemBuilder: (BuildContext context, int index) {
                  return ListTile(title: Text('Item $index'));
                },
              ),
            );
          },
        ),
      ),
    );
  }
}
