Set Min Width and Min Height of a Container

In some cases, you may need to set a minimum width and height for a Container. These examples will show you how to do this using the minWidth and minHeight properties of the Container widget to limit the padding within a Container.

BoxConstraints is the class which defines min and max size for box layout.

Container(
          color: Colors.orange,
          constraints: BoxConstraints(
              minHeight: 200, minWidth: double.infinity),
          child: ListView(
            shrinkWrap: true,
            children: [
              ...List.generate(
                100,  
                (index) => Text(
                  'Text: ${index}'
                ),
              ),
            ],
          ),
        )

@override
  Widget build(BuildContext context) {
    return Padding(
      padding: const EdgeInsets.fromLTRB(0, 8.0, 0, 8.0),
      child: Container(
        padding: const EdgeInsets.all(8.0),
        decoration: BoxDecoration(
            color: MyTheme.cardColor,
            border: Border.all(
              color: MyTheme.cardColor,
            ),
            borderRadius: MyTheme.radius),
        child: Row(
          mainAxisAlignment: MainAxisAlignment.start,
          crossAxisAlignment: CrossAxisAlignment.start,
          children: [
            Expanded(
              flex: 9,
              child: Column(
                mainAxisAlignment: MainAxisAlignment.start,
                crossAxisAlignment: CrossAxisAlignment.start,
                children: [
                  RowField(

                              stockQuant!.purchase_uom[1])),
                      right: LabelValue(
                          label: "Loose Qty",
                          value: _showQty(stockQuant!.loose_qty,
                              stockQuant!.product_uom[1])),
                      flexes: [5, 5]),
                  RowField(

                ],
              ),
            ),
            Expanded(child: IconButton(onPressed: () {
              Navigator.push(
