Lessons Learned

  • I used an boilerplate which has MVVM structure and base classes. It had base view for stateless widgets. I added dynamic base view for StatefulWidget.

  • I used L10n to localization. I made the error messages suitable for l10n by using static methods without depending on context.

  • I used Firebase as backend service. I solved the user verification process from within the application using the mail service. (Because there is no custom mail operation like OTP mail in Firebase.) Read the case from Medium
