@abhith What version Flutter use for build this project?

Abhith Rajan · Answer 2 · Wed Mar 16 2022 23:22:44 GMT+0800 (China Standard Time)

@wstagf I don't exactly remember the flutter version last I had before I upgraded to 2.10.2.
I recently tried to upgrade (flutter 2.10.2) and it got stuck because of a plugin open issue (this). And the progress was pushed to flutter-upgrade branch.

So, thought of waiting a bit more to resolve the plugin issue to go ahead with the upgrade.

And related to the Null Safety, yeah when I turned it on, there were so many issues with the code (of course), so thought of going little by little, again, waiting for the build to succeed to resolve them.

Thiago Augusto · Answer 3 · Thu Mar 17 2022 21:26:01 GMT+0800 (China Standard Time)

Yesterday I have some attents to update, but no success... Has libs no support nullsafety... In next weekend trying again.

Abhith Rajan · Answer 4 · Thu Mar 17 2022 21:30:19 GMT+0800 (China Standard Time)

What I'm trying at the moment is to,

Create a fresh flutter project
Then copy the old code and at least make it build successfully (without Null Safety at first)
Then look into the Null Safety

Thiago Augusto · Answer 5 · Thu Mar 17 2022 21:44:43 GMT+0800 (China Standard Time)

I think don`t work because onesignal uses deprecated plugin...

In this repo I commit my changes and attents. https://github.com/wstagf/piggyvault

Abhith Rajan · Answer 6 · Fri Mar 18 2022 02:46:14 GMT+0800 (China Standard Time)

The flutter upgrade was completed successfully and is building fine.

Next is to look into Null Safety.
And it feels like it gonna take time since when I enabled it, the number of errors are around 624.
