plugin dependency only for specific platform?

[Thomas Verbeek]

Hey,

is it possible to include a dependency only for a sepcific platform?

I am developing a cross-plattform app fro macOS and iOS and are using the shared_preferences plugin. in pubspec.yaml I added this:

  shared_preferences: ^0.5.3+4

  shared_preferences_fde:

    path: ../../flutter-desktop-embedding/plugins/flutter_plugins/shared_preferences_fde

Building for macOS works, but I have to comment out the line starting with shared_preferences_fde for iOS builds - otherwise it fails.

Thx,

Tom.

There isn't a way to make a plugin a dependency only on one platform. The issue you are hitting is https://github.com/flutter/flutter/issues/39659, and the solution will be to make dependencies on non-iOS plugin a no-op on iOS rather than failing to build.

In the meantime, feel free to submit a PR to flutter-desktop-embedding to add a dummy iOS podspec to that plugin, which is the current workaround; see https://github.com/google/flutter-desktop-embedding/tree/master/plugins/flutter_plugins/url_launcher_fde/ios for an example.
