Flutter list widgets

Single-child layout widgets Align . A widget that aligns its child within itself and optionally sizes itself based on the child’s size . AspectRatio. A widget that attempts to size the child to a specific aspect ratio.

In Flutter, almost everything is a widget—even layout models are widgets . The images, icons, and text that you see in a Flutter app are all widgets. But things you don’t see are also widgets, such as the rows, columns, and grids that arrange, constrain, and align the visible widgets.

In Flutter, LayoutBuilder Widget is similar to the Builder widget except that the framework calls the builder function at layout time and provides the parent widget’s constraints.
