Modified Authentication Part as per issue #101

[AmanNegi]

Proposed Changes

• Added a check during Login and Signup to ensure the user is using a valid app version. If the user login is successful but the app version is not supported the user is now directed to the Update App page.

• The Error dialog displayed was showing the error in an uneasy fashion, I modified the error dialog as well. Changes I made in Error Dialog are:

  • Made the Errors alignment to CrossAxisAlignment.start.
  • The key property of the error was coming all lowercase, I added a few lines of code to ensure the first letter was capitalized to ensure the error was more formal and readable.

• Now the user login process is much more streamlined with the loading indicator, error handling dialog and app version validator.
