InjectedTextEditing class abstract

Inject a TextEditingController

This injected state abstracts the best practices to come out with a simple, clean, and testable approach deal with TextField and form validation.

The approach consists of the following steps:

   final email =  RM.injectTextEditing():
  • Instantiate an InjectedTextEditing object using RM.injectTextEditing
  • Link the injected state to a TextField (No need to TextFormField even inside a OnFormBuilder). 
       TextField(
      controller: email.controller,
      focusNode: email.focusNode, //It is auto disposed of.
      decoration:  InputDecoration(
          errorText: email.error, //To display the error message.
      ),
      onSubmitted: (_) {
          //Focus on the password TextField after submission
          password.focusNode.requestFocus();
      },
  ),
