How to capitialize first letter of TextFormField in flutter


I’m trying to capitialize the first letter of Textformfield, for this i’m using the

textCapitalization: TextCapitalization.words,

but it’s not working for Textformfield, and works for textfield

please help how to do this.


You can try with formatter for upper case, in TextFormField you just use UpperCaseTextFormatter class in input formatters section

            controller: _textEditingController,
            inputFormatters: <TextInputFormatter>[

Upper text formatter

class UpperCaseTextFormatter extends TextInputFormatter {
  TextEditingValue formatEditUpdate(TextEditingValue oldValue, TextEditingValue newValue) {
    return TextEditingValue(
      text: capitalize(newValue.text),
      selection: newValue.selection,
String capitalize(String value) {
  if(value.trim().isEmpty) return "";
  return "${value[0].toUpperCase()}${value.substring(1).toLowerCase()}";
