Hi Steve, Thank you for the great tutorial. I learned about the token refresh mechanism (which I couldn't find anywhere) in this tutorial, and I will use it with Google Classroom APIs. Excellent style of teaching, by the way. Regards

[@the_digitalpro]

Thank you so much you are welcome. To be honest it's such a great technique which can be applied to other platforms it does not get the exposure it deserves. Glad you found it useful.

Great video ! I've already started implementing it but I had a doubt. To avoid repeating the action on all pages that make API requests, what is your suggestion for checking whether the token is still valid for each API request in a unique way? Include the action inside main?

[@the_digitalpro]

Hmmm. Perhaps an App level Action Block instead of Page level Action Block. So long as it gives you access to what you need to perform a simple check you should be golden.

Hello steve. Very grateful to you from the bottom of my heart. I learned many thing from you. I have a proposal, Can you please start a series of tutorial video on making a quiz app, where we can serve question from firebase according to topic, and user can take exam from the app, can see his/her score. Also, it will be better, if we can post blog and article on the quizzes topic m regular just like your content management system app. User will read blogs topic basis daily and then he can take exam through quizzes. Any additional features may added by you. Also you may demonstrate setup premium app purchase system integration. Where user will have two option, either use the app with ads or have to buy the premium version. Thank you for your kindness to read my comment. Thanks again. You are my idol, you are my inspiration.

Hello thank you for your amazing comments. I really do appreciate it. I like the idea of a quiz app and it would be a great topic for another series of tutorials. The challenge here of course is building something which is as close to nocode as possible so I need to sit down and consider what options I have. Quite often with Firebase you would likely reach out to some cloud functions to perform some calculations. Alternatively of course you can do this in FlutterFlow by way of a custom function to perform calculations and then store the result back to Firebase. Let me have a think about it.

[@the_digitalpro]

Just for your info. The FlutterFlow team have created a Firebase Quiz App using Firebase that you might be interested to clone. Checkout app.flutterflow.io/project/f-f-form-builder-pwhnli

Its great to hear from you dear. I'm hopeful that you will think well and you will start the series. Thanks for your valuable time@@the_digitalpro

[@user-ty5px9xh8w]

I'm checking. Thanks for the info.

[@user-ty5px9xh8w]

please start the video playlist with quiz app with AI like uploading any pdf and AI automaticaly serve question based on the particular pdf, i dont know either it will work or not but if not please make quiz app with all regular features. thank you steve. @@the_digitalpro

Hey mate, thanks for the great content, really appreciate your support. I have zero coding experience nor do i work in IT industry. I am learning no code tools just to keep up with changing time and your videos help me a lot. I have a request, can you please make a tutorial to build OCR app using Google ml kit from pub dev within flutterflow. Thanks again, cheers !

Hi, i need to implement refresh token with Azure Ad Authentication, you think its possible with your process ? thx

[@bob_factory]

Nice idea, but this seems like it has a edge case problem that during evaluation the token is valid but while making an api call it gets expired in which you will get an error. I am trying to solve this from the other side where if any returns a 401 error then I refresh the token or log thge user out. But the problem is how to do this in a listview while paginating. Any thoughts would be appreciated

[@seka9910]

Hey Steve, I am getting a strange error and it looks like it's coming from the *isTokenExpired* custom function. Any ideas? (extracted from console): Error: FormatException: Invalid length, must be multiple of four (at character 632) ...MzMtYWFiNjA0ZGM4ODVlIn0sInN0LWV2Ijp7InQiOjE3MTM1NDAwNjE4MjIsInYiOmZhbHNlfX0 ^ at Object.throw_ [as throw] (dart_sdk.js:11914:11) at convert._Base64Decoder.new.close (dart_sdk.js:56383:19) at Base64Decoder.convert (dart_sdk.js:56319:15) at Base64Codec.decode (dart_sdk.js:55910:27) at Object.isTokenExpired (custom_functions.dart:23:46) at refreshToken (actions.dart:12:61) at refreshToken.next () ...

[@the_digitalpro]

This looks really odd. I need to fire up the final app example and try this myself. Something may have changed and its not obvious from the error log you posted. Did you try the final project at all?

[@manshilkanhai2578]

Hey Steve, @ 15:10, should it not be Result instead of Results?

[@the_digitalpro]

Yes absolutely later in the video I corrected it. 😀

[@DeSofSistemas]

hello, this method is used to give a temporary authentication that, for example, expires in 48 hours?

[@the_digitalpro]

Main token will expire in 1 hour. Refresh token is 100 days.

[@ezzabbas8561]

Any news about supabase with flutterflow app that you told ?

[@the_digitalpro]

Hello. Hope you are good. Can you confirm which FlutterFlow app you are referring too?

[@ezzabbas8561]

I think you said you are preparing for creating full app with flutterflow using most of supabase features.@@the_digitalpro
