A collection of Flutter Hooks inspired by React's react-use library. This monorepo contains multiple packages providing different categories of hooks for Flutter development.

📦 Packages

Package	Description	Version
flutter_use	Core hooks library with essential utilities
flutter_use_audio	Audio playback and control hooks
flutter_use_battery	Battery state monitoring hooks
flutter_use_geolocation	Location and permission hooks
flutter_use_network_state	Network connectivity hooks
flutter_use_sensors	Device sensors hooks
flutter_use_video	Video playbook hooks

🚀 Installation

For the core package:

flutter pub add flutter_use

For specialized packages:

flutter pub add flutter_use_audio    # Audio hooks
flutter pub add flutter_use_battery  # Battery hooks
# ... and so on

• useFirstMountState — check if current build is first.
• useBuildsCount — count component builds.

🎨 Development & Debugging

Core package: flutter_use

• useLogger — logs in console as component goes through life-cycles.

📱 Device Sensors

Package: flutter_use_sensors

• useAccelerometer, useUserAccelerometer, useGyroscope, and useMagnetometer — tracks accelerometer, gyroscope, and magnetometer sensors.

Core package: flutter_use

• useOrientation — tracks state of device's screen orientation.
• useOrientationFn — calls given function when screen orientation changes.

🔋 Device Information

Package: flutter_use_battery

• useBattery — tracks device battery state.

Package: flutter_use_geolocation

• useGeolocation — tracks geo location and permission state of user's device.

Package: flutter_use_network_state

• useNetworkState — tracks the state of apps network connection.

🎵 Media
