GetIt V4 release candidate is out

[escamoteur]

Hi,

I uploaded the release candidate for V4 on pub: https://pub.dev/packages/get_it/versions/4.0.0-release-candidate

Please give it a try. It contains:

• Breaking changes in API!!! and also to the beta before!!
• Release candidate
• New Async functions
• Factories with parameters
• Improved startup synchronisation
• add isRegistered method #41
• readyFuture does not complete if signalReady() is called first #33
• Register factories that take parameters #29

Please also read the documentation and tell me here if something isn't clear or even better make an PR on the readme file ;-)

Is there a migration guide for the breaking changes?

[escamoteur]

The changes are minimal so shouldn't be a problem this time. If you need help just ask here.

[ThinkDigitalSoftware]

Yes, been waiting for #41. Thank you!

[Kavantix]

Really like what you ended up with for the async factory/singletons!

[escamoteur]

Thanks!

I was just hitting the fact that my async singletons were not loading 'in-time' yesterday and found this new version published. Great additions!

John
