Flutter: allow overflow within a container?

Question

Is it possible to allow overflow within a container WITHOUT making that content scrollable? For example:

Container(
  height: 100,
  width: MediaQuery.of(context).size.width,
  child: Row(
    children: List.generate(10, (i) => Container(height: 100.0, width: 300).toList();
   ),
)

I know that it will theoretically work correctly in release, but I'm looking to suppress the overflow warnings while debugging.

I've tried wrapping the Container() in OverflowBox(), but it still shows the overflow warning. Everything else I've tried makes the list scrollable - it needs to stay fixed.

Use listviewbuilder widget

To make the List NOT scrollable, use NeverScrollableScrollPhysics() in ListView.
For example

ListView.builder(
          physics: NeverScrollableScrollPhysics(),
          scrollDirection: Axis.horizontal,
          itemCount: 100,
          itemBuilder: (context, i) {
            return Container(
              height: 100.0,
              width: 300,
              margin: EdgeInsets.all(8),
              color: Colors.green,
            );
          },
        ),

Use SingleChildScrollView whith scrollDirection set to Axis.horizontal, Although it works I recommend ListViewBuilder

Container(
          height: 100,
          width: MediaQuery.of(context).size.width,
          child: SingleChildScrollView(
            scrollDirection: Axis.horizontal,
            child: Row(
              children: List.generate(
                10,
                (i) => Container(
                  height: 100.0,
                  width: 300,
                  margin: EdgeInsets.all(8),
                  color: Colors.green,
                ),
              ).toList(),
            ),
          ),
        ),

using ListviewBuilder

ListView.builder(
              scrollDirection: Axis.horizontal,
              itemCount: 100,
              itemBuilder: (context, i) {
                return Container(
                  height: 100.0,
                  width: 300,
                  margin: EdgeInsets.all(8),
                  color: Colors.green,
                );
              },
            )

EDIT: Wrap widget will do the trick.

SizedBox(
        height: 100,
        width: MediaQuery.of(context).size.width,
        child: Wrap(
          clipBehavior: Clip.hardEdge,
          direction: Axis.horizontal,
          children: List.generate(
            10,
            (i) => Container(
              height: 100.0,
              width: 300,
              margin: EdgeInsets.all(8),
              color: Colors.green,
            ),
          ).toList(),
        ),
      ),

Thanks for your answer - though I need the content to NOT be scrollable. I'm wondering if that is possible with flutter (without the SDK complaining)?
