How do I supply an initial value to a text field?

Question

I\'d like to supply an initial value to a text field and redraw it with an empty value to clear the text. What\'s the best approach to do that with Flutter\'s APIs?

Answer 1

If you want to handle multiple TextInputs as asked by @MRT in the comment to the accepted answer, you can create a function that takes an initial value and returns a TextEditingController like this:

initialValue(val) {
  return TextEditingController(text: val);
}

Then, set this function as the controller for the TextInput and supply its initial value there like this:

controller: initialValue('Some initial value here....')

You can repeat this for the other TextInputs.
