simple_permissions_native 0.0.1

Unified permission handling for Flutter apps. Manages runtime permissions, app roles (SMS, Dialer), and battery optimization.

simple_permissions

Federated permission and capability plugin for Flutter.

Provides a typed, cross-platform capability API for checking and requesting device permissions. Android runtime permissions, app roles (SMS / Dialer), and battery optimization are handled natively; iOS supports contacts, notifications, and media library access.

Platform Support

Platform	Status
Android	✅ Full (permissions, roles, battery optimization)
iOS	✅ Contacts, notifications, media (images/video/audio)
macOS / web / Linux / Windows	No-op — all capabilities return granted

Installation

dependencies:
  simple_permissions: ^0.3.0

Quick Start

import 'package:simple_permissions_native/simple_permissions.dart';

// Initialize once at app startup
await SimplePermissions.initialize();

// High-level intention check (routes through capabilities internally)
final ready = await SimplePermissions.instance.check(Intention.texting);
if (!ready) {
  await SimplePermissions.instance.request(Intention.texting);
}

// Granular capability check
final grant = await SimplePermissions.instance.checkCapability(
  PermissionCapability.canReadContacts,
);
if (grant != PermissionGrant.granted) {
  await SimplePermissions.instance.requestCapability(
    PermissionCapability.canReadContacts,
  );
}

// Multi-capability detailed result
final result = await SimplePermissions.instance.requestDetailedCapabilities(
  Intention.texting.capabilities,
);
if (result.requiresSettings) {
  await SimplePermissions.instance.openAppSettings();
} else if (result.isFullyGranted) {
  // All permissions secured — proceed.
}

API Reference

Primary API (capability-based)

Method	Returns	Description
initialize()	Future<void>	Must be called before any other method
check(Intention)	Future<bool>	Quick boolean — are all capabilities for the intention granted?
request(Intention)	Future<bool>	Request all capabilities for an intention
checkCapability(PermissionCapability)	Future<PermissionGrant>	Check a single capability
requestCapability(PermissionCapability)	Future<PermissionGrant>	Request a single capability
checkDetailedCapabilities(List<PermissionCapability>)	Future<CapabilityResult>	Batch check with per-capability detail
requestDetailedCapabilities(List<PermissionCapability>)	Future<CapabilityResult>	Batch request with per-capability detail
openAppSettings()	Future<bool>	Open the OS settings page for the app

CapabilityResult

Returned by checkDetailedCapabilities and requestDetailedCapabilities:

Getter	Type	Description
capabilities	Map<PermissionCapability, PermissionGrant>	Per-capability grant status
isFullyGranted	bool	All are granted or notApplicable
isReady	bool	Alias for isFullyGranted
hasDenial	bool	Any capability was denied
hasPermanentDenial	bool	Any capability was permanentlyDenied
requiresSettings	bool	User must go to settings to unblock
denied	List<PermissionCapability>	Capabilities that were denied
permanentlyDenied	List<PermissionCapability>	Capabilities that require settings

PermissionGrant enum

granted · denied · permanentlyDenied · restricted · limited · notApplicable

PermissionCapability enum

canSendMessages · canReadMessages · canReceiveMessages · canMakeCalls · canAnswerCalls · canReadPhoneState · canReadContacts · canWriteContacts · canPostNotifications · canReadMediaImages · canReadMediaVideo · canReadMediaAudio · canReadExternalStorage · canBypassBatteryOptimizations · canBeDefaultMessagingApp · canBeDefaultDialerApp

Intention enum

Groups capabilities by use-case:

Intention	Capabilities
texting	SMS send/receive, MMS receive, read SMS/MMS, role, battery
calling	Phone calls, phone state, answer calls, call log, dialer role
contacts	Read + write contacts
device	Read phone state
fileAccess	Media images, video, audio
notifications	Post notifications

Deprecated API

The following methods still work but will be removed in a future release. See @Deprecated annotations in source for migration guidance.

checkPermissions, requestPermissions, checkDetailed, requestDetailed, isRoleHeld, requestRole, isIgnoringBatteryOptimizations, requestBatteryOptimizationExemption, shouldShowRequestPermissionRationale, shouldShowRationale

The PermissionResult class is also deprecated in favour of CapabilityResult.

Migration from 0.2.x → 0.3.0

// Before (0.2.x)
final result = await SimplePermissions.instance.checkPermissions(
  Intention.texting.permissions,
);
final isHeld = await SimplePermissions.instance.isRoleHeld(Intention.texting.role!);

// After (0.3.0)
final result = await SimplePermissions.instance.checkDetailedCapabilities(
  Intention.texting.capabilities,
);
// result.isFullyGranted covers permissions + role in one call

Key changes:

• Capability API is primary. check() and request() now route through checkDetailedCapabilities / requestDetailedCapabilities internally.
• CapabilityResult replaces PermissionResult — cross-platform, typed.
• Intention.permissions and Intention.role are deprecated. Use Intention.capabilities instead.
• All string-based methods (checkPermissions, isRoleHeld, etc.) are deprecated.
• Battery optimization is explicit. If your app previously used isIgnoringBatteryOptimizations()/requestBatteryOptimizationExemption(), migrate to: checkCapability(PermissionCapability.canBypassBatteryOptimizations) and requestCapability(PermissionCapability.canBypassBatteryOptimizations).

iOS Setup

For iOS capability requests to show system permission prompts, the host app must include usage description keys in ios/Runner/Info.plist:

• Minimum iOS version: 14.0

Capability	Info.plist Key
canReadContacts / canWriteContacts	NSContactsUsageDescription
canReadMediaImages / canReadMediaVideo	NSPhotoLibraryUsageDescription
canReadMediaAudio	NSMicrophoneUsageDescription
canPostNotifications	(none required)

<key>NSContactsUsageDescription</key>
<string>This app needs access to your contacts to display conversations.</string>
<key>NSPhotoLibraryUsageDescription</key>
<string>This app needs access to your photo library to send and view media.</string>
<key>NSMicrophoneUsageDescription</key>
<string>This app needs microphone access to send audio messages.</string>

Notes

• Call SimplePermissions.initialize() before using instance methods.
• Concurrent request operations of the same type are rejected with PlatformException(code: "request-in-progress").
• Android API-level normalization is built in: READ_EXTERNAL_STORAGE → not required on API 33+; READ_MEDIA_* / POST_NOTIFICATIONS → not required below API 33.
• iOS returns PermissionGrant.notApplicable for Android-only capabilities (roles, battery, SMS send/receive).
• Other unsupported platforms use the noop fallback and return granted.
