How to get the TextField value in flutter

another easier (for my opinion) option is to add 'onChanged' property inside the TextField class that will contain the String

String enteredText .... TextField( onChanged: (newText) { enteredText = newText; },

Create your TextEditingController as a global variable in your State class and set it into your TextField widget.

TextEditingController emailController = new TextEditingController();

....


TextField(
  controller: emailController,
  obscureText: true,
  textAlign: TextAlign.left,
  decoration: InputDecoration(
    border: InputBorder.none,
    hintText: 'PLEASE ENTER YOUR EMAIL',
    hintStyle: TextStyle(color: Colors.grey),
  ),
)

Now you can get the value using :

emailController.text
