flutter_screentime 0.1.5

Flutter plugin for Screen Time style blocking with host-configured iOS extensions and configurable Android overlays.

flutter_screentime

日本語版 README

Flutter plugin for Screen Time style blocking.

The package now splits concerns this way:

• The plugin owns the Flutter API, Android foreground overlay service, and iOS native bridge.
• The host iOS app owns Screen Time extension targets, entitlements, signing, and final shield-screen presentation.

Demo

iOS

Android

What the plugin does

• Requests authorization on iOS and opens the required settings screens on Android.
• Presents FamilyActivityPicker on iOS to capture blocked app selections.
• Applies ManagedSettingsStore shielding on iOS for the selected apps and categories.
• Runs a configurable Android overlay for blocked apps.
• Persists block-screen configuration into shared storage so host iOS extensions can render custom screens.

Dart API

const screenTime = FlutterScreentime();

await screenTime.setSharedContainerId('group.your.app');
await screenTime.configureBlockScreen(
  const ScreenTimeBlockScreenConfig(
    title: 'Focus mode',
    message: 'This app is blocked right now.',
    backgroundColorHex: '#0F172A',
    textColorHex: '#F8FAFC',
    primaryButtonLabel: 'Open app',
    secondaryButtonLabel: 'Settings',
  ),
);

await screenTime.requestAuthorization();
await screenTime.selectBlockedApps();
await screenTime.startBlocking();

iOS extension model

Custom blocked screens are still a host-app concern. This plugin stores the configuration, but the host app must add:

• Shield Configuration Extension
• Device Activity Monitor Extension, if needed
• a shared App Group
• the Family Controls capability

Setup details: doc/ios_extensions.md

Templates:

• ShieldConfigurationExtension.swift.sample
• DeviceActivityMonitorExtension.swift.sample

Android notes

Android does not have an equivalent Screen Time API, so the plugin uses:

• SYSTEM_ALERT_WINDOW
• PACKAGE_USAGE_STATS
• a foreground service overlay

If you do not set blocked packages explicitly, the Android implementation blocks all launchable non-system apps except the host app itself.
