Flutter Duskmoon

Flutter DuskMoon UI Design System

Complete component library for Flutter apps with codegen-driven theming, adaptive (Material/Cupertino) widgets, platform-aware settings UI, feedback helpers, and data visualization.

Quick Start

Umbrella package (recommended)

Add duskmoon_ui to get theme, widgets, settings, feedback, forms, visualization, theme BLoC, and code-engine primitives in one import:

# pubspec.yaml
dependencies:
  duskmoon_ui: ^1.6.0

import 'package:duskmoon_ui/duskmoon_ui.dart';

Individual packages

dependencies:
  duskmoon_theme: ^1.6.0           # Theme only
  duskmoon_widgets: ^1.6.0         # Adaptive widgets, markdown, chat
  duskmoon_settings: ^1.6.0        # Settings UI
  duskmoon_feedback: ^1.6.0        # Dialogs, toasts, snackbars
  duskmoon_form: ^1.6.0            # BLoC-based form management
  duskmoon_visualization: ^1.6.0   # Data visualization charts
  duskmoon_theme_bloc: ^1.6.0      # BLoC persistence
  duskmoon_adaptive_scaffold: ^1.6.0  # Responsive scaffold
  duskmoon_code_engine: ^1.6.0     # Code editor engine

Skill Modules

Detailed documentation is split by package:

• duskmoon_ui.md — Umbrella package direct exports and DmEditorTheme
• duskmoon_theme.md — Theme system, color schemes, text themes, extensions
• duskmoon_widgets.md — Adaptive widgets (Material/Cupertino/Fluent) plus markdown rendering, markdown input, chat, and code editor
• duskmoon_settings.md — Platform-aware settings UI (Material/Cupertino/Fluent)
• duskmoon_feedback.md — Dialogs, snackbars, toasts, bottom sheets
• duskmoon_form.md — BLoC-based form state management with adaptive field builders and field BLoCs
• duskmoon_visualization.md — Data visualization: line, bar, scatter, heatmap, network graph, map chart
• duskmoon_theme_bloc.md — BLoC for persisting theme via SharedPreferences
• duskmoon_adaptive_scaffold.md — Responsive scaffold with M3 adaptive layout, breakpoints, and slot-based composition
• duskmoon_code_engine.md — Pure Dart code editor engine with 19 language grammars, incremental parsing, and syntax highlighting

Minimal App Example

import 'package:flutter/material.dart';
import 'package:duskmoon_ui/duskmoon_ui.dart';

void main() => runApp(const MyApp());

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      theme: DmThemeData.sunshine(),
      darkTheme: DmThemeData.moonlight(),
      themeMode: ThemeMode.system,
      home: const HomePage(),
    );
  }
}

class HomePage extends StatelessWidget {
  const HomePage({super.key});

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: DmAppBar(title: const Text('DuskMoon App')),
      body: Center(
        child: DmButton(
          onPressed: () => showDmSuccessToast(
            context: context,
            message: 'Hello from DuskMoon!',
          ),
          child: const Text('Tap me'),
        ),
      ),
    );
  }
}

Architecture Overview

duskmoon_theme              <- Pure theme, zero external deps
    +-- duskmoon_theme_bloc <- BLoC for theme persistence
    +-- duskmoon_widgets    <- Adaptive widgets + markdown + chat + code editor
    |       +-- duskmoon_code_engine (for DmCodeEditor)
    +-- duskmoon_settings   <- Settings UI (Material/Cupertino/Fluent)
    +-- duskmoon_feedback   <- Dialogs, snackbars, toasts, bottom sheets
    +-- duskmoon_form       <- BLoC-based form management (depends on theme + widgets)
    +-- duskmoon_visualization <- Data visualization charts (depends on theme)
    +-- duskmoon_code_engine <- Pure Dart code editor (re-exported by umbrella)
            |
        duskmoon_ui         <- Umbrella: re-exports primary packages
                               Provides DmEditorTheme (fromTheme, sunshine, moonlight)

duskmoon_code_engine        <- Pure Dart code editor (standalone)
duskmoon_adaptive_scaffold  <- Responsive scaffold (forked, independently versioned)

duskmoon_ui does not directly export duskmoon_adaptive_scaffold; import that package separately for low-level scaffold APIs.

Conventions

• All public classes use Dm prefix
• Factory classes are abstract final with static methods
• Generated token files use .g.dart suffix in src/generated/
• BLoC classes (user-subclassable) keep original names (e.g., FormBloc, TextFieldBloc); only UI widgets get Dm prefix
• Platform resolution is 4-tier: widget platformOverride -> DmPlatformOverride InheritedWidget -> DuskmoonApp -> Theme.of(context).platform
• DmPlatformStyle has 3 values: material, cupertino, fluent
