First public release of flutter_simple_contact - a lightweight, transparent contact fetching plugin for Flutter with zero third-party dependencies.

✨ Features #

Core Functionality

• Android Support: Full support for Android API 21+ using native ContactsContract provider
• iOS Support: Full support for iOS 13.0+ using native CNContactStore Contacts framework
• Zero Dependencies: No third-party packages - direct native implementation only
• Lightweight: ~5KB package size for maximum efficiency

Contact Modes

• Unified Contacts: Fetch aggregated contacts (default, works on both platforms)
• Raw Contacts: Fetch per-account raw contacts (Android only)
• Automatic fallback handling for platform-specific limitations

Permission Management

• Built-in Permission Handling: Automatic runtime permission requests
• Manual Permission Mode: Disable auto-handling for custom flows
• Permission Status Tracking: Detailed error codes for denied/permanently denied states
• Platform-specific permission dialogs (Material for Android, Cupertino for iOS)

Data Fetching Options

Minimal Mode (minimizeData: true)

• Contact ID
• Display name
• Phone numbers with labels
• Photo availability flag
• Starred/favorite status (Android only)
• Last modified timestamp (Android only)

Full Metadata Mode (minimizeData: false)

• All minimal mode fields, plus:
• Email addresses with labels

• Websites with labels
• Organizations (company, department, job title)
• Notes (iOS: requires entitlement; Android: included)

Filters

Sorting

Advanced Features

🔒 Security & Privacy #

• Transparent source code (auditable by enterprises)
• No data sent to third parties
• Respects platform permission models
• Optional minimal data collection mode
• Clear permission rationale requirements

📱 Platform-Specific Implementations #

Android

• Uses ContactsContract.Contacts for unified contacts
• Uses ContactsContract.RawContacts for raw contact mode
• Queries ContactsContract.Data table for rich metadata (emails, addresses, websites)
• Runtime permission handling via ActivityCompat
• Supports filters: starred, hasPhoto, hasPhone
• Returns lastModifiedMillis timestamp where available

iOS

• Uses CNContactStore.enumerateContacts for efficient fetching
• keysToFetch optimization to avoid unauthorized key errors
• Conditional CNContactNoteKey based on includeNotes flag
• Handles .notDetermined, .denied, .restricted, .authorized states
• Returns structured postal addresses with ISO country codes
• Organization data (company, department, job title) from contact fields

🛠️ APIs #

Methods

• FlutterSimpleContact.fetchContactsRaw(): Returns raw maps
