helperMaxLines property
final
The maximum number of lines the helperText can occupy.
Defaults to null, which means that the helperText will be limited to a single line with TextOverflow.ellipsis.
This value is passed along to the Text.maxLines attribute of the Text widget used to display the helper.
See also:
- errorMaxLines, the equivalent but for the errorText.
Implementation
final int? helperMaxLines;
