[BUG] Major Isar upgrade causing compilation errors due to incorrect versioning

[HappyMakadiyaS]

What is the bug?

Isar has been upgraded with Braking changes due to that FMTC throwing error while running the application.

Pub.dev has Analysis issue as well

Could you please fix it on priority? This is a blocker for us for a production application we are working on.

Platforms Affected

Requirements

• I agree to follow this project's Code of Conduct

• I have completed the pre-report checks listed on the docs site
• If I am using FMTC in a proprietary project, I have read and understood this important legal notice

@HappyMakadiyaS I have not yet claimed support for Isar v3.1. Unfortunately their change was breaking, but they did not follow semver. Now the package resolver forces usage of v3.1, even though FMTC is only compatible with v3.0.

As a workaround, please use dependency overrides to pin the Isar dependency to v3.0.6-dev.0.

[JaffaKetchup]

In addition, I have reason to believe you are breaking the terms of the GPL license. If your application is proprietary, please get in touch through email.
This also applies to Simform Solutions @SimformSolutionsPvtLtd (cc @dhaval-k-simformsolutions).

@JaffaKetchup
Thanks for the quick reply. We are not supposed to break any licence agreement here. We are just checking the feasibility of this package with our use case, if its fits in our use case we surely reach out to you for licence purchase things. Hope my answers makes sense to you. Please let me know any correction needed at my end.

Also pin all related packages to the same version, like 'isar_flutter_libs'.

[JaffaKetchup]

@HappyMakadiyaS Sure, no problem. Please get in touch when you get a moment (github@jaffaketchup.dev), just to acknowledge that you're currently evaluating it, just so I can keep track of things.

See the Important Temporary Notice posted on the front page of https://fmtc.jaffaketchup.dev/ for more information about this issue and its workarounds.

This has been fixed in #114. Thanks for all your perseverance!
