Log bug against aws-amplify use of componentWillReceiveProps instead of getDerivedStateFromProps

Describe the bug In reference to aws-amplify-react-native/src/Auth/ConfirmSignUp.js

https://github.com/aws-amplify/amplify-js/blob/master/packages/aws-amplify-react-native/src/Auth/ConfirmSignUp.js

This react component still implements componentWillReceiveProps whereas this has been deprecated since React 16.3. This class should be updated to use getDerivedStateFromProps. This probably applies to all the Auth components.

To Reproduce Steps to reproduce the behavior:

1. Implement an Auth workflow using AWS-Amplify
2. When confirm sign up screen appears, the “username” field is blank

Expected behavior The username field should be pre-filled, because the user just signed up on the previous screen.

Actual behavior The field is blank.

Smartphone:

• Tested on iPhone 8
• iOS 12.1

React Native + TypeScript + Jest I got a warning:

Warning: componentWillReceiveProps has been renamed, and is not recommended for use. See https://fb.me/react-unsafe-component-lifecycles for details.

Rename componentWillReceiveProps to UNSAFE_componentWillReceiveProps to suppress this warning in non-strict mode. In React 17.x, only the UNSAFE_ name will work. To rename all deprecated lifecycles to their new names, you can run npx react-codemod rename-unsafe-lifecycles in your project source folder.

Please update the following components: ConfirmSignUp

* Move data fetching code or side effects to componentDidUpdate.
* If you're updating state whenever props change, refactor your code to use memoization techniques or move it to static getDerivedStateFromProps. Learn more at: https://fb.me/react-derived-state
