google_wallet_button

Unofficial UI-only Flutter widgets for "Add to Google Wallet" and "View in Google Wallet" buttons with automatic locale detection and official branding assets. This package provides the button UI — it does not integrate with the Google Wallet Passes API. You are responsible for handling the onPressed callback to create and save passes.

Inspired by the official Compose counterpart https://github.com/google-wallet/compose-wallet-button.

Features

• Two button types: AddToGoogleWalletButton and ViewInGoogleWalletButton
• Two styles per type: primary (full-width) and condensed (badge)
• ~70 localized SVG assets for "Add to" and ~75 for "View in"
• Automatic locale detection from ambient Localizations
• Manual locale override possible (locale parameter)
• Custom height (width derived from aspect ratio)
• Disabled state (pass null to onPressed)
• Accessibility via Semantics
