Null safety

[venkatd]

All of our dependencies are null safe so it would be nice for this to be null safe as well. Any chance we could sponsor you for a few hours to upgrade it to null safety?

Sure, I can do it sometime next week, but my buy me a coffee book page seems broken for some reason. Will also fix that soon.

[venkatd]

Turns out we won't end up using auth0 for our app, but happy to buy you a book anyway. Let me know once it's fixed :)

Hey, was studying Type Script for this, and busy for some other things as well. Now here are some update on this.

• the buy me a coffee book page works now in here https://www.buymeacoffee.com/anthonychwong.
• because Auth0 API treat null and undefined (variable not set) differently while dart only have null, there are some extra work at the moment to verify proper values are passed to the API or change the wrapper if that is not possible

[anthonychwong]

It is now published here 0.0.1-alpha.6.

Not working on our project We get this with

auth0_flutter_web: ^0.0.1-alpha.6

Error: Cannot run with sound null safety, because the following dependencies
don't support null safety:

 - package:auth0_flutter_web

This is because the plugin does not support strong-mode

strong-mode: implicit-casts: false implicit-dynamic: false

[anthonychwong]

@vanlooverenkoen For some reason pud.dev really like the old package 0.0.1-alpha.20210224 a lot and treat this as the latest one, even when checking null safety.

I tried to pin to 0.0.1-alpha.6 (by removing the prefixed head ^), than my testing project compiles. Please let me know if this works for you.

[vanlooverenkoen]

It has nothing to do with the versions. The plugin does not support strongmode

Add the following to your analyis_options.yml

implicit-casts: false
implicit-dynamic: false

And you will not be able to compile your project.

@vanlooverenkoen In my testing project, those are enabled as well. and the output looks well.
