What it does

Flutter macOS Duplicate Camera Plugin is an agent skill from divinevideo/divine-mobile. Fix Flutter macOS build failure caused by duplicate camera plugins. Use when: (1) macOS build fails with "Ambiguous use of 'CameraMacosPlugin.register(with:)'" error, (2) Both cameramacos and cameramacosplus are in pubspec.yaml, (3) Build worked before adding a new camera package. The plugins define the same class name causing Swift registration conflicts.

Its SKILL.md is about 860 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Mobile, covering Cross-platform mobile apps and iOS development. It works with macOS, Flutter and Xcode. The licence is MPL-2.0.

When your agent uses it

  • MacOS build fails with Ambiguous use of CameraMacosPlugin.register(with:) error
  • Both cameramacos and cameramacosplus are in pubspec.yaml
  • Build worked before adding a new camera package

Example prompts

  • “Ambiguous use of”
  • “/flutter-macos-duplicate-camera-plugin”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Identify the duplicates - Check pubspec.yaml for both packages
  2. Choose one to keep - camera_macos_plus is generally preferred as it's a
  3. Remove the duplicate from pubspec.yaml
  4. Clean thoroughly - The Xcode build system may be in a corrupted state
  5. Rebuild

What it can do on your machine

Read from SKILL.md and the folder at commit 8d5fbf2. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • flutter

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • pub.dev
    • docs.flutter.dev

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Flutter macOS Duplicate Camera Plugin loads about 862 tokens when it runs. Until then it costs about 100 tokens; SKILL.md has 249 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~100
When it runs · the whole SKILL.md, loaded when a task matches
~862

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Flutter macOS Duplicate Camera Plugin Fix

Problem

Flutter macOS builds fail when both camera_macos and camera_macos_plus packages are present in pubspec.yaml. Both packages define the same CameraMacosPlugin class, causing Swift registration ambiguity.

Context / Trigger Conditions

Error message:

Ambiguous use of 'CameraMacosPlugin.register(with:)'

Symptoms:

  • macOS build fails during Swift compilation
  • iOS build may still succeed (different plugin implementations)
  • Error occurs in the generated plugin registration code
  • May be accompanied by Xcode build system crashes or "stat cache file not found" errors

Common scenarios:

  • Project has camera_macos for basic camera support
  • Added camera_macos_plus for additional features
  • Transitive dependency pulled in duplicate plugin
  • Copied pubspec.yaml from another project with different camera requirements

Solution

  1. Identify the duplicates - Check pubspec.yaml for both packages:

    yaml
    # Look for these:
camera_macos: ^0.0.9
camera_macos_plus: ^0.0.3

  2. Choose one to keep - camera_macos_plus is generally preferred as it's a more feature-complete fork of camera_macos

  3. Remove the duplicate from pubspec.yaml:

    yaml
    # Keep only one:
camera_macos_plus: ^0.0.3  # macOS camera support

  4. Clean thoroughly - The Xcode build system may be in a corrupted state:

    bash
    flutter clean
rm -rf build/
rm -rf macos/Pods/
rm -f macos/Podfile.lock
rm -rf ~/Library/Developer/Xcode/DerivedData/Runner-*
flutter pub get

  5. Rebuild:

    bash
    flutter build macos

Verification

After the fix:

  • flutter build macos completes successfully
  • No "Ambiguous use" errors in build output
  • The macOS app launches and camera functionality works

Example

Before (broken):

yaml
dependencies:
  camera_macos_plus: ^0.0.3
  divine_camera:
    path: packages/divine_camera
  camera_macos: ^0.0.9  # DUPLICATE - causes conflict

After (fixed):

yaml
dependencies:
  camera_macos_plus: ^0.0.3  # macOS camera support (replaces camera_macos)
  divine_camera:
    path: packages/divine_camera
  # camera_macos removed

Notes

  • camera_macos_plus is a community fork with additional features
  • If you specifically need camera_macos instead, remove camera_macos_plus
  • Check transitive dependencies with flutter pub deps if duplicates reappear
  • The Xcode build system can get into corrupted states after this error; thorough cleaning (including DerivedData) may be required
  • This is specific to macOS - iOS uses different camera plugin implementations
