cache hooks data and return when connectivity isn't available

[vibern0]

A good example is beneficiary data.

Currently, it is implemented on the wallet, caching with the redux state. See here.

But this can be abstracted to the utils also giving support to the web.

Example

// update async storage when a beneficiary or community state changes
// only after the hook data is ready
useEffect(() => {
    if (isReady) {
        import('@react-native-async-storage/async-storage').then(({ default: AsyncStorage}) => {
            AsyncStorage.setItem('@im-utils/cache', JSON.stringify({ beneficiary, community }));
        });
    }
}, [beneficiary, community, isReady]);

// initial load
useEffect(() => {

    import('@react-native-async-storage/async-storage').then(({ default: AsyncStorage}) => {
        AsyncStorage.getItem('@im-utils/cache').then(console.log);
    });

    // (...)
}, [currentBlockNumber]);
