maxLines property

int? maxLines
final

Specifies the maximum number of lines the selected value can display in the DropdownMenu.

If the provided value is 1, then the text will not wrap, but will scroll horizontally instead. Defaults to 1.

If this is null, there is no limit to the number of lines, and the text container will start with enough vertical space for one line and automatically grow to accommodate additional lines as they are entered, up to the height of its constraints.

If this is not null, the provided value must be greater than zero. The text field will restrict the input to the given number of lines and take up enough horizontal space to accommodate that number of lines.
