react-native-last-active-state

The library determines the time of the last active state of the application.

🚀 Motivation

When an application is destroyed, it does not receive control, thus there is no way to detect the time spent in an inactive state. This library remembers the time of the last active state, you can get it the next time you start the application.

🎮 Usage

import LastActiveState from "@kode-frontend/react-native-last-active-state";

export default function App() {
    const [result, setResult] = React.useState<number | undefined>(
        LastActiveState.initialLastActiveTime
    );

    React.useEffect(() => {
        const listener = LastActiveState.addListener(({ lastActiveTime }) => {
            setResult(lastActiveTime);
        });
        return () => {
            listener.remove();
        };
    }, []);

  return (
        <View>
            <Text>Last active time: {result}</Text>
            <Button
                onPress={() =>
                Alert.alert(
                    'Last active time',
                    String(LastActiveState.getLastActiveTimeSync())
                )
                }

            />
        </View>
  );
}
