inputFormatters property

List<TextInputFormatter> inputFormatters
final

A list of input formatters which can validate the text as it is being typed.

If you specify this parameter, the default input formatters aren't used, so make sure you really check for everything (like length of the input).

Sample code

An code input that displays a normal keyboard but only allows for hexadecimal input:

CodeInput(
  inputFormatters: [
    FilteringTextInputFormatter.allow(RegExp('^[0-9a-fA-F]*\$'))
  ]
)

Implementation

final List<TextInputFormatter> inputFormatters;
