Description

Migrated the ButtonHero component from metamask-mobile to design-system-react-native following the patterns established in PR #912 (ADR-0003 and ADR-0004).

What is the reason for the change?
The ButtonHero component was only available in metamask-mobile and needed to be migrated to the shared design system for consistency and reusability across platforms.

What is the improvement/solution?

  • Implemented ButtonHero component with ThemeProvider pattern locking to light theme colors
  • Created comprehensive test suite with accessibility testing
  • Added Storybook stories for all major props (Size, IsFullWidth, StartIconName, EndIconName, Disabled, Loading)
  • Documented component following cross-platform consistency standards
  • Added ButtonHeroSize type alias for cross-platform compatibility

Related issues

Fixes: https://consensyssoftware.atlassian.net/browse/DSYS-290

Manual testing steps

  1. Run Storybook: yarn storybook:ios or yarn storybook:android
  2. Navigate to Components/ButtonHero
  3. Test all stories: Default, Size, IsFullWidth, StartIconName, EndIconName, Disabled, Loading
  4. Verify light theme colors are applied regardless of device theme setting
  5. Test press interactions and verify accessibility features

Screenshots/Recordings

Before

Component only available in metamask-mobile

After

Component now available in design-system-react-native with:

  • Light theme lock (ThemeProvider pattern)
  • Full prop support matching React web implementation
  • Comprehensive accessibility features
  • Complete documentation and tests
buttonhero-stories-demo.mp4

Pre-merge author checklist

  • I've followed MetaMask Contributor Docs
  • I've completed the PR template to the best of my ability
  • I've included tests if applicable
  • I've documented my code using JSDoc format if applicable
  • I've applied the right labels on the PR (see labeling guidelines). Not required for external contributors.

Pre-merge reviewer checklist

  • I've manually tested the PR (e.g. pull and build branch, run the app, test code being changed).
  • I confirm that this PR addresses all acceptance criteria described in the ticket it closes and includes the necessary testing evidence such as recordings and or screenshots.

Implementation Details

Key Features

  • ThemeProvider Pattern: Uses the same pattern from metamask-mobile with ButtonHeroInner wrapped in ThemeProvider with Theme.Light
  • Design Tokens: Uses bg-primary-default, text-primary-inverse, and bg-primary-default-pressed classes
  • Cross-Platform Consistency: Props and behavior match the React web implementation
  • Comprehensive Testing: 11 test cases covering all functionality including accessibility

Files Created

  • ButtonHero.tsx - Main component implementation
  • ButtonHero.types.ts - Type definitions extending ButtonBaseProps
  • ButtonHero.test.tsx - Comprehensive test suite
  • ButtonHero.stories.tsx - Storybook stories
  • README.md - Component documentation
  • index.ts - Barrel exports

Files Modified

  • packages/design-system-react-native/src/types/index.ts - Added ButtonHeroSize alias
  • packages/design-system-react-native/src/components/index.ts - Added ButtonHero and ButtonHeroSize exports

Test Results

✅ All linting checks passed
✅ All builds passed
✅ All tests passed (11/11 ButtonHero tests + all existing tests)


Note

Low Risk
Adds a new exported button component and a size alias without changing existing button behavior; risk is mainly around styling/theme expectations and public API surface expansion.

Overview
Introduces a new ButtonHero component in design-system-react-native, implemented as a thin wrapper around ButtonBase that locks styling to the light theme via ThemeProvider and applies hero-specific background/text/pressed classes.

Adds supporting Storybook stories, a comprehensive React Native test suite (press/disabled/loading/accessibility + pressed-state styling), component documentation, and exports ButtonHero/ButtonHeroProps from the components barrel along with a new ButtonHeroSize alias (ButtonBaseSize).

Co-Authored-By: Claude <noreply@anthropic.com>
Add tests for pressed state handling in ButtonHero:
- Test interactive button applies pressed styles
- Test disabled button does not apply pressed styles
- Test loading button does not apply pressed styles

These tests exercise the ternary operator in ButtonHero.tsx line 24
that was previously uncovered, bringing branch coverage from 40% to 100%.

Cursor Bugbot has reviewed your changes and found 1 potential issue.

Bugbot Autofix prepared a fix for the issue found in the latest run.

  • ✅ Fixed: Spread props override hero styling class names
    • Destructured styling props and merged twClassName into a variant callback so consumer props no longer override hero styles.

+## Accessibility
+
+ButtonHero includes built-in accessibility features:

+- **Accessibility Hint**: Auto-generated for loading state
+
+### Custom Accessibility Props
+
+You can override the default accessibility behavior:
+
+```tsx
+<ButtonHero
+  accessibilityLabel="Primary action"
+  accessibilityHint="Performs the main action"
+>
+  Hero Button
+</ButtonHero>
+```
+
+## Theme
+
+ButtonHero is **locked to light theme** colors regardless of the app's theme setting. It uses:
+
+- Background: `bg-primary-default` (light theme)
+- Text: `text-primary-inverse` (light theme)
+- Pressed: `bg-primary-default-pressed` (light theme)
+
+This ensures consistent branding for high-impact actions across different theme modes.

 /**
  * Button - variant

… tests

- Replace toBeDefined() with toBeOnScreen() for better test semantics
- Remove three pressed state tests that only checked element existence without asserting actual behavior
- Fix story names to follow PascalCase convention (IsDisabled, IsLoading)
- Destructure and ignore twClassName, textClassName, iconClassName to prevent overriding hero-specific light theme styling
- Clarify JSDoc comments to explain prop destructuring pattern
- Make pressed parameter explicit in className functions (required by ButtonBase type signature)
Remove all #### Example section headers to align with the component documentation template format where code examples follow directly after prop tables without intermediate headers

Story names follow PascalCase convention matching prop names. IsDisabled and IsLoading match their respective isDisabled and isLoading props per component documentation standards.

Test uses helper functions flattenStyles and expectBackground from ButtonPrimary pattern to verify actual Tailwind background color values rather than just checking component existence.

expectBackground(btn.props.style, 'bg-primary-default');
expect(btn).toBeDefined();
});

ReactTestRenderer enables testing dynamic style functions with pressed state. This validates the conditional logic at line 31 that prevents pressed styles when disabled or loading.

Icon tests use testID pattern from ButtonBase to verify icons actually render rather than just checking button existence. This ensures startIconName and endIconName props work correctly.

ButtonHeroInner destructures and ignores twClassName, textClassName, and iconClassName props with underscore prefix. This prevents consumers from accidentally overriding the locked light theme styling which is essential for brand consistency.

Conditional pressed state logic checks both isDisabled and isLoading flags. This ensures pressed background only applies when button is interactive, preventing confusing visual feedback during disabled or loading states.

ThemeProvider with Theme.Light wraps the entire component to force light theme colors. This ensures ButtonHero maintains consistent brand appearance regardless of the app theme mode.

## Release 24.0.0

This release includes BadgeCount type migration updates and new React
Native components.

### 📦 Package Versions

- `@metamask/design-system-shared`: **0.3.0**
- `@metamask/design-system-react`: **0.10.0**
- `@metamask/design-system-react-native`: **0.10.0**

### 🔄 Shared + React Type Updates

#### BadgeCount ADR Migration (#942)

Updated `BadgeCount` types to follow ADR-0003 and ADR-0004 patterns
across shared, React, and React Native packages.

**What Changed:**
- `BadgeCountSize` now uses const-object + string-union typing instead
of enum-based typing
- Shared `BadgeCount` props/types are centralized in
`@metamask/design-system-shared`
- Platform packages consume and re-export shared `BadgeCount` types

**Impact:**
- Consistent type architecture across packages
- Better alignment with design-system ADRs
- Potentially breaking for enum-specific consumer type usage

### 📱 React Native Updates (0.10.0)

#### Added
- Added `ActionListItem` component (#951)
- Added `SensitiveText` component (#922)
- Added `ButtonSemantic` component (#950)
- Added `BottomSheetHeader` component (#927)
- Added `ButtonHero` component to React Native package (#934)

### ⚠️ Breaking Changes

- `BadgeCount` type exports were migrated from enum-style to
const-object/union style (#942)
- Continue importing from package entrypoints, but update enum-specific
type assumptions in consuming code

### ✅ Checklist

- [x] Changelogs updated with human-readable descriptions
- [x] Changelog validation passed (`yarn changelog:validate`)
- [x] Version bumps follow semantic versioning
  - design-system-shared: minor (0.2.0 → 0.3.0)
  - design-system-react: minor (0.9.0 → 0.10.0)
  - design-system-react-native: minor (0.9.0 → 0.10.0)
- [x] Breaking changes documented with migration guidance
- [x] PR references included in changelog entries

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> **Low Risk**
> Changes are limited to version bumps and changelog updates; no runtime
code is modified. The main risk is downstream impact from the documented
breaking `BadgeCount` type export migration when consumers upgrade.
> 
> **Overview**
> Bumps the monorepo and package versions for the `24.0.0` release
(`@metamask/design-system-react`/`react-native` to `0.10.0`,
`@metamask/design-system-shared` to `0.3.0`).
> 
> Updates changelogs to publish release notes, including a **breaking**
`BadgeCount` type export migration to the const-object + string-union
pattern and documenting newly added React Native components in `0.10.0`.
