![]() For example, if the buttons overflow and ButtonBar.alignment was set to MainAxisAlignment.start, the buttons would align to the horizontal start of the button bar. The key difference is that the MainAxisAlignment will then be treated as a cross-axis/horizontal alignment. When the Directionality is TextDirection.ltr, the button bar’s children are right justified and the last child becomes the rightmost child. The children are laid out in a Row with MainAxisAlignment.end. If the button bar’s width exceeds the maximum width constraint on the widget, it aligns its buttons in a column. In flutter, ButtonBar places the buttons horizontally according to the buttonPadding. What I want is either all on the same row, or every button on a separate row. If there are more buttons, example short, short, looong, wrap will put the ones it can on the same row, ( short, short, long). It can be as simple as giving the Buttons as children but there are other structural preferences that a ButtonBar provides. That works for this specific example, where there are only two buttons.

For example, if the buttons overflow and ButtonBar.alignment was set to MainAxisAlignment.start, the buttons would align to the horizontal start of the button.
