codepush_ios

The iOS bytecode patch applier for codepush.

Add it only if you patch iOS:

dependencies:
  codepush: ^0.1.0
  codepush_ios: ^0.1.0

Why this is a separate package

It calls dart:_internal.applyCodePushPatch, which exists only in a Flutter engine built with --dart-dynamic-modules. A direct call to it does not fail at runtime — it fails at kernel compilation, with Method not found.

So if codepush depended on it, every app using CodePush could only be built with the forked engine. Including flutter run in debug, and including Android, which needs no fork at all because its patch is a libapp.so the stock engine already knows how to load.

Keeping the call here is what lets an Android-only app, and every developer's debug build, use a stock Flutter SDK.

You do not import this

The entrypoint codepush release ios generates registers the applier before main(). Nothing in your lib/ mentions it.
