How do you use TextField to flutter?

Input is done by calling the getText() .

You can use something like this in the following code: _formKey. currentState. save(); calls the onSaved() on each textFormField items, which assigns the value to all the fields and you can use them as required.

We know that Flutter does not have an ID like in Android for the TextField widget. Flutter allows the user to retrieve the text in mainly two ways: First is the onChanged method, and another is the controller method.
