• Works on Web, Android, iOS, macOS, Linux, and Windows.
• See per-phase notes below for the API surface.

Phase 5 — Diff editor, multi-model, custom themes #

• Diff editor: MonacoDiffEditor widget + MonacoDiffController. Side-by-side and inline modes via renderSideBySide. Separate original/modified content streams.
• Custom themes: MonacoThemes.defineTheme(name, MonacoTheme(base, rules, colors)) + MonacoThemes.setTheme(name) wrapping monaco.editor.defineTheme / setTheme.
• Multi-model: controller.createModel / switchToModel / disposeMonacoModel for IDE-style tab switching (models are independent of editors).
• Bridge JS handlers for all three.

Phase 4 — Native platform (webview) #

• flutter_monaco_editor_native package: MonacoNative.register() installs webview-based hooks into the main package.
• NativeMonacoBridge over webview_flutter with JavaScriptChannel + runJavaScript.
• One WebView per editor (documented limitation).

Phase 3 — Language providers #

• MonacoLanguages.register{Completion,Hover,SignatureHelp,Definition}Provider.
• Dart-side async providers via JS ↔ Dart round-trip through the bridge.

Phase 2 — Decorations, markers, actions, commands #

• deltaDecorations, setModelMarkers, addAction, addCommand, trigger.
• Key constants: MonacoKeyMod, MonacoKeyCode.

Phase 1 — Core #

• 1.1 Package scaffolding + bundled Monaco 0.55.1.
• 1.2 Shared JS bridge + web transport via dart:js_interop.
• 1.3 MonacoController + event streams.
• 1.4 MonacoEditorOptions (~60 typed fields + rawOptions escape hatch).
