I have previously ended up using a validator to process the user input, and removing the extra space there. If spaces are not allowed, you could also .strip() the value in the value changed callback.

Take a look at the simple validator example from the docs: text form field with validation.

And there, you could have something like this:

valideInput(value) {
  // strip trailing spaces
  value = value.strip();

  // actual validation like empty checks
  if (value == null || value.length == 0) return 'Please enter a value!';

  return null;
}

// Completetly successful 

setState(() {
      formatedEmail = emailC.text.replaceAll(' ', '');
});
