LengthLimitingTextInputFormatter constructor Null safety
- int? maxLength,
- {MaxLengthEnforcement? maxLengthEnforcement}
Creates a formatter that prevents the insertion of more characters than a limit.
The maxLength must be null, -1 or greater than zero. If it is null or -1 then no limit is enforced.
Implementation
LengthLimitingTextInputFormatter(
this.maxLength, {
this.maxLengthEnforcement,
}) : assert(maxLength == null || maxLength == -1 || maxLength > 0);
