Bootstrap Grid Implementation

bootstrap_grid

Responsive Grid Layout and List for Flutter - Forked and improved

This package has no third-party layout dependencies. Grid tiers use Bootstrap-style width breakpoints from MediaQuery.

Breakpoints

BootstrapCol spans are selected from the current window width:

Tier	Minimum width
xs	< 576
sm	≥ 576
md	≥ 768
lg	≥ 992
xl	≥ 1200
xxl	≥ 1600

Unset larger tiers fall back to the next smaller defined span.

Responsive Grid Layout

With BootstrapRow and BootstrapCol you can get the same behavior of bootstrap Grid System

Give every col the width it shall occupy at every size category assuming the total width is 12

        BootstrapRow(
          children: [
            BootstrapCol(
              lg: 12,
              child: Container(
                height: 100,
                alignment: Alignment(0, 0),
                color: Colors.purple,
                child: Text("lg : 12"),
              ),
            ),
            BootstrapCol(
              xs: 6,
              md: 3,
              child: Container(
                height: 100,
                alignment: Alignment(0, 0),
                color: Colors.green,
                child: Text("xs : 6 \r\nmd : 3"),
              ),
            ),
            BootstrapCol(
              xs: 6,
              md: 3,
              child: Container(
                height: 100,
                alignment: Alignment(0, 0),
                color: Colors.orange,
                child: Text("xs : 6 \r\nmd : 3"),
              ),
            ),
            BootstrapCol(
              xs: 6,
              md: 3,
              child: Container(
                height: 100,
                alignment: Alignment(0, 0),
                color: Colors.red,
                child: Text("xs : 6 \r\nmd : 3"),
              ),
            ),
            BootstrapCol(
              xs: 6,
              md: 3,
              child: Container(
                height: 100,
                alignment: Alignment(0, 0),
                color: Colors.blue,
                child: Text("xs : 6 \r\nmd : 3"),
              ),
            ),
        )

Responsive Grid List

BootstrapList works differently in that you only specify a desired width for the items and spacing, and it will decide how many items shall fit in a line, and the width of the item and spacing will change (only small change) to fill the entire width

    BootstrapList(
        desiredItemWidth: 100,
        minSpacing: 10,
        children: [
          1,
          2,
          3,
          4,
          5,
          6,
          7,
          8,
          9,
          10,
          11,
          12,
          13,
          14,
          15,
          16,
          17,
          18,
          19,
          20
        ].map((i) {
          return Container(
            height: 100,
            alignment: Alignment(0, 0),
            color: Colors.cyan,
            child: Text(i.toString()),
          );
        }).toList()
    )
