### Start Metro Server

Source: https://github.com/douglasjunior/react-native-applifecycle/blob/main/Sample/README.md

Starts Metro, the JavaScript bundler for React Native. This command should be run from the root of your React Native project.

```bash
# using npm
npm start

# OR using Yarn
yarn start
```

--------------------------------

### Install react-native-applifecycle

Source: https://github.com/douglasjunior/react-native-applifecycle/blob/main/README.md

Installs the react-native-applifecycle package using either yarn or npm.

```bash
yarn add react-native-applifecycle
```

```bash
npm i -S react-native-applifecycle
```

--------------------------------

### Run React Native Application

Source: https://github.com/douglasjunior/react-native-applifecycle/blob/main/Sample/README.md

Launches your React Native application on an Android emulator or iOS simulator. Ensure the Metro server is running in a separate terminal.

```bash
# For Android
# using npm
npm run android

# OR using Yarn
yarn android

# For iOS
# using npm
npm run ios

# OR using Yarn
yarn ios
```

### Modify and Reload React Native App

Source: https://github.com/douglasjunior/react-native-applifecycle/blob/main/Sample/README.md

Instructions on how to modify your React Native application code and reload the changes on Android and iOS devices/simulators.

```bash
# For Android: Press R twice or use Developer Menu (Ctrl+M or Cmd+M)

# For iOS: Press Cmd+R in the iOS Simulator
```

### Get Current App Lifecycle State with Hook

Source: https://github.com/douglasjunior/react-native-applifecycle/blob/main/README.md

Utilizes the `useAppLifecycle` hook to get the current lifecycle state of the application. This hook simplifies state management for lifecycle events.

```tsx
import {useAppLifecycle} from 'react-native-applifecycle';

const App = () => {
  const currentLifecycle = useAppLifecycle();

  // do something

  return <View />;
}
```

--------------------------------

### Jest Mock for react-native-applifecycle

Source: https://github.com/douglasjunior/react-native-applifecycle/blob/main/README.md

Provides a Jest mock implementation for the react-native-applifecycle module, allowing for easier testing of components that depend on it.

```js
jest.mock('react-native-applifecycle/dist/AppLifecycle', () => require('react-native-applifecycle/jest/AppLifecycleMock'));
```

--------------------------------

### App Lifecycle API - addEventListener Method

Source: https://github.com/douglasjunior/react-native-applifecycle/blob/main/README.md

The `addEventListener` method allows setting up a listener for specified event types on the AppLifecycle. It takes an event type and a callback function that receives the current app state.

```ts
static addEventListener(
  type: AppStateEvent,
  listener: (state: AppStateStatus) => void,
): NativeEventSubscription;
```

--------------------------------

### App Lifecycle API - currentState Property

Source: https://github.com/douglasjunior/react-native-applifecycle/blob/main/README.md

The `currentState` property provides the current state of the application lifecycle.

```ts
static currentState: AppStateStatus;
```

--------------------------------

### Subscribe to App Lifecycle Change Listener

Source: https://github.com/douglasjunior/react-native-applifecycle/blob/main/README.md

Subscribes to the 'change' event from AppLifecycle to receive updates on the application's state. It's important to remove the listener when the component unmounts to prevent memory leaks.

```tsx
import {AppLifecycle} from 'react-native-applifecycle';

const App = () => {

  useEffect(() => {
    const listener = AppLifecycle.addEventListener('change', state => {
      // do something
    });

    return () => listener.remove();
  }, []);

  return <View />;
}

export default App;
```
