Thanks for taking care of this!

Can you explain more the motivation for the last two commits?
53577d7 zulip plugin: Use flutter.compileSdkVersion for compileSdk
c7fbd6e zulip plugin: Switch to compilerOptions from kotlinOptions

(E.g., does something go wrong without them?)

Otherwise, these changes all LGTM.

does something go wrong without them?

No nothing goes wrong, just some cleanup and trying to match our android/app/build.gradle for the app.

• 53577d7 zulip plugin: Use flutter.compileSdkVersion for compileSdk

  • This is to match our android/app/build.gradle, and similar to a change that happend for Flutter's first-party plugins: flutter/packages@bfad6b9

• c7fbd6e zulip plugin: Switch to compilerOptions from kotlinOptions

  • This is related to Switch to compilerOptions from kotlinOptions in Gradle scripts #1804, and does the same migration for zulip_plugin.

Ah OK, makes sense. Please explain that in the commit messages, then :-) — that's the readable permanent record of why we did things.

Thanks for the review @gnprice! Pushed an update, PTAL.

Thanks! LGTM, and looks good in manual testing on an iOS simulator. Marking for Greg's review.

Thanks @rajveermalviya for the revision, and @chrisbobbe for testing this! Merging, with two nits fixed:

     To match our `android/app/build.gradle`, and it is similar to a
-    change that happened for Flutter's first-party plugins:
-      flutter/packages@bfad6b9
+    change earlier this year for Flutter's first-party plugins:
+      flutter/packages@bfad6b976

Use at least 9 hex digits (vs. just 7) to mention a commit ID:
https://github.com/zulip/zulip-mobile/blob/main/docs/style.md#mentioning-commits

7 hex digits, which is what GitHub shows in its UI whenever it doesn't show 40, is short enough that there's a material risk of collisions: in zulip.git there are already a handful of commits that are ambiguous when identified by just 7 digits, and in a very large project like the Linux kernel such collisions can become routine.

-    zulip plugin: Use flutter.compileSdkVersion for compileSdk
+    zulip_plugin: Use flutter.compileSdkVersion for compileSdk

-    zulip plugin: Switch to compilerOptions from kotlinOptions
+    zulip_plugin: Switch to compilerOptions from kotlinOptions

I think the phrase "Zulip plugin" isn't particularly self-explanatory for what this subtree does, so the identifier zulip_plugin is a clearer way to refer to it.

(It looks like these are the first commits touching this subtree since it was introduced in 058f184, so this is basically the first time we're picking a commit-message prefix to use for it.)
