flutter-theming-apps

flutter-theming-apps is a skill for Claude Code, Codex from build-with-dhiraj/ai-workflow-framework-portability-kit. It costs 29 tokens per session (1,802 once invoked), scanned A, original, MIT.

Guidance for controlling the shared visual style of a Flutter app. A theme is a set of common choices such as colors, text styles, button appearance, and spacing that can apply across many screens.

In plain words
What is it for?
Use it to define app-wide colors and typography, customise buttons and other components, override styles for part of a screen, and support platform-specific appearance.
Why use it?
It avoids repeating visual settings in every widget and helps keep the interface consistent. It also explains Material 3, Google's current design system for Flutter, and adaptive designs for different platforms.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

flutter-theming-apps scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Implementing Flutter Theming and Adaptive Design

Contents

Core Theming Concepts

Flutter applies styling in a strict hierarchy: styles applied to the specific widget -> themes that override the immediate parent theme -> the main app theme.

  • Define app-wide themes using the theme property of MaterialApp with a ThemeData instance.
  • Override themes for specific widget subtrees by wrapping them in a Theme widget and using Theme.of(context).copyWith(...).
  • Do not use deprecated ThemeData properties:
    • Replace accentColor with colorScheme.secondary.
    • Replace accentTextTheme with textTheme (using colorScheme.onSecondary for contrast).
    • Replace AppBarTheme.color with AppBarTheme.backgroundColor.

Material 3 Guidelines

Material 3 is the default theme as of Flutter 3.16.

  • Colors: Generate color schemes using ColorScheme.fromSeed(seedColor: Colors.blue). This ensures accessible contrast ratios.
  • Elevation: Material 3 uses ColorScheme.surfaceTint to indicate elevation instead of just drop shadows. To revert to M2 shadow behavior, set surfaceTint: Colors.transparent and define a shadowColor.
  • Typography: Material 3 updates font sizes, weights, and line heights. If text wrapping breaks legacy layouts, adjust letterSpacing on the specific TextStyle.
  • Modern Components:
    • Replace BottomNavigationBar with NavigationBar.
    • Replace Drawer with NavigationDrawer.
    • Replace ToggleButtons with SegmentedButton.
    • Use FilledButton for a high-emphasis button without the elevation of ElevatedButton.

Component Theme Normalization

Component themes in ThemeData have been normalized to use *ThemeData classes rather than *Theme widgets.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
