Steps to reproduce

  1. Configure a Linux custom-devices entry (platform: linux-x64) and flutter config --enable-custom-devices --enable-native-assets.
  2. Use a project whose dependency tree includes any package with a hook/build.dart that is normally only relevant on another platform — e.g. dev/integration_tests/new_gallery reproduces this directly.
  3. flutter run -d <custom-device-id> (or flutter build bundle).

Expected results

The asset bundle builds. Code-asset hooks that emit nothing for OS.linux (like objective_c) should not block the build, and no native (CMake) compiler match is required because a custom device / bundle build has no native app build.

Actual results

Target dart_build failed: Error: Could not read compiler configurations for build hooks, expected
build/flutter_assets/linux/x64/debug/CMakeCache.txt to exist.
