Getting started

dart pub global activate obsidian_dart

Create your entry point at bin/plugin_entry.dart:

import 'package:obsidian_dart/obsidian_dart.dart';

void main() {
  bootstrapPlugin(
    onLoad: (plugin) async {
      plugin.addCommand(
        id: 'hello',
        name: 'Say hello from Dart',
        callback: () => showNotice('Hello from Dart!'),
      );
    },
    onUnload: (plugin) async {},
  );
}

Build and copy to your vault:

dart run obsidian_dart:obsidian_build --plugin-id my_plugin
dart run obsidian_dart:obsidian_manifest --plugin-id my_plugin
# copy build/plugin/my_plugin/ → <vault>/.obsidian/plugins/my_plugin/
