CupertinoFormRow class
An iOS-style form row.
Creates an iOS-style split form row with a standard prefix and child widget. Also provides a space for error and helper widgets that appear underneath.
The child parameter is required. This widget is displayed at the end of the row.
The prefix parameter is optional and is displayed at the start of the row. Standard iOS guidelines encourage passing a Text widget to prefix to detail the nature of the row's child widget.
The padding parameter is used to pad the contents of the row. It defaults to the standard iOS padding. If no edge insets are intended, explicitly pass EdgeInsets.zero to padding.
The helper and error parameters are both optional widgets targeted at displaying more information about the row. Both widgets are placed underneath the prefix and child, and will expand the row's height to accommodate for their presence. When a Text is given to error, it will be shown in CupertinoColors.destructiveRed coloring and medium-weighted font.
