ResponsiveRow

ResponsiveRow borrows the idea of grid layout from Bootstrap web framework.

ResponsiveRow allows aligning child controls to virtual columns. By default, a virtual grid has 12 columns, but that can be customized with ResponsiveRow.columns property.

Similar to expand property, every control now has col property which allows specifying how many columns a control should span. For example, to make a layout consisting of two columns spanning 6 virtual columns each:

import flet as ft

ft.ResponsiveRow([
    ft.Column(col=6, controls=[ft.Text("Column 1")]),
    ft.Column(col=6, controls=[ft.Text("Column 2")])
])

ResponsiveRow is "responsive" because it can adapt the size of its children to a changing screen (page, window) size. col property in the example above is a constant number which means the child will span 6 columns for any screen size.

If ResponsiveRow's child doesn't have col property specified it spans the maximum number of columns.

col can be configured to have a different value for specific "breakpoints". Breakpoints are named dimension ranges:

Breakpoint	Dimension
xs	<576px
sm	≥576px
md	≥768px
lg	≥992px
xl	≥1200px
xxl	≥1400px

For example, the following example collapses content into a single column on a mobile device and takes two columns on larger screens:

import flet as ft

ft.ResponsiveRow([
    ft.Column(col={"sm": 6}, controls=[ft.Text("Column 1")]),
    ft.Column(col={"sm": 6}, controls=[ft.Text("Column 2")])
])
