@jmagman and @hellohuanlin in case you would like to take a look

[hellohuanlin]

what's initialization logic? do you mean app delegate?

[leighajarett]

Yes exactly

A few nits. You know, it strikes me that this page would be well suited to be a 3-column table with a "Swift/Objective-C column, a Flutter column, and a Comments column. It would greatly reduce a lot of boilerplate text.

@leighajarett : I have some suggestions here. After you revise, I'll have another look.

I like the idea of using a table for this doc, is there an example in our docs that you could send over so I can adapt it?

Also, I want to be clear that this is not a doc for 1P plugins. It references plugins that are also 3P. I only included plugins that are widely used by the community. But I am happy to include a sentence in this doc somewhere that says something like "some of the plugins referenced in this doc are built and maintained by members of the Flutter community" to make it clear (or some language are the idea that this is not an endorsement). Let me know what you think!

we may also wanna include database, which is pretty common: https://docs.flutter.dev/cookbook/persistence/sqlite

can mention native uses either CoreData or sqlite, and flutter use this plugin

[leighajarett]

I've changed some of the wording based on feedback around the title / description. I also added the "persisting data" piece (following @hellohuanlin's input on SQLite) and added a sentence saying we're not endorsing packages listed (feel free to propose a better way to message this). As a quick aside, I've only included 3P plugins that have high scores on pub.

Last, I also formatted it as a table, as suggested by @atsansone. But, it could use some formatting :)

[hellohuanlin]

Table for the win

[leighajarett]

Thanks for the formatting, looks good to me! Is there anyone else that needs to review @atsansone?
