@kukkok3 The --platform chrome option is soon going to be removed completely without any replacement, we cannot use it, otherwise on next upgrade these tests will break

@dtscalac Sorry I just saw your comment.

• I dont want to remove the native tests, I'll just add a target to run tests on web as well. If the platform chrome will be removed we can disable that target.
• I looked trough the flutter repo and the only issue I could find related to removing the flag is this one From what I can read I dont think the flag will be removed any time soon adn they are well aware that flag is used outside flutter as well.
• There are recent issues opened regarding bugs with this flag and seems like flutter devs are still supporting it
• We worked under the assumption that flutter works the same on every platform. As it turns out this is not true. For example ( besides the issue with numbers ) we use a database that uses a different library to support native or web. Turns out our tests are using a native implementation while in the app we are using the web implementation. How I'm supposed to test this stuff? How do I know what changes between flutter compiled for native and flutter compiled for web? I could not find such a list.
  I'm open to suggestions but so far I cannot find any other option other then run unit tests on web as well

Please rename it as well in: https://github.com/input-output-hk/catalyst-voices/blob/main/catalyst_voices/justfile#L26

This package was designed as pure dart package, it means it should have no dependency on flutter. For testing we use test package, not flutter_test. What's the reason to include the flutter_test package?

this package has no tests and won't have them, do we need the test framework here?

[dtscalac]

Shouldn't be required for this package
