FlexibleGrid

Version GitHub license

A bare-bones flexible grid for dynamic layouts in Flutter.

Usage

FlexibleGrid behaves similarly to a simple Column or Row, just add your children and let it lay everything out. It does not have inherent scrolling, you need to handle that, this is truly a bare-bones widget to simply lay everything out.

FlexibleGrid(
  columnCount: 3,
  enforceRowHeight: true,
  useTightConstraints: true,
  children: [
    FlexibleGridItemProxy(columnSpan: 2, child: Container(color: Colors.green, height: 100)),
    Container(color: Colors.red, height: 75),
    Container(color: Colors.blue, height: 150),
    Container(color: Colors.yellow, height: 125),
    Container(color: Colors.purple, height: 100),
  ],
)
When enforceRowHeight & useTightConstraints is true: When enforceRowHeight & useTightConstraints is false:

Parameters

Parameter Description
columnCount Controls how many children are laid out in a row. Defaults to 2. Must be greater than 0.
verticalSpacing Sets the vertical spacing between children. Defaults to 0. Must be greater than 0.
horizontalSpacing Sets the horizontal spacing between children. Defaults to 0. Must be greater than 0.
enforceRowHeight Whether children are set to be the height of the row they are in or can be less.
useTightConstraints Whether children will be stretched out even with fixed size due to using BoxConstraints.tightFor. With this, you need to rebuild the grid yourself when item sizes change, as the grid won't repaint itself automatically.
children Widgets to be displayed.

FlexibleGridItemProxy

To make a child span multiple columns, wrap it in a FlexibleGridItemProxy widget:

FlexibleGrid(
  columnCount: 3,
  children: [
    FlexibleGridItemProxy(
      columnSpan: 2,
      child: Container(color: Colors.green, height: 100),
    ),
    Container(color: Colors.red, height: 75),
    // ... more children
  ],
)
Parameter Description
columnSpan Number of columns this item should span. Must be greater than 0.
child The widget to display.
