How to Save the Passing Screen After a User Has Passed the Test Even When the App Exits in React Native
If you want your app to remember the passing screen after a user has passed the test even when the app exits in React Native, there are several ways to achieve this.
Method 1 - Using AsyncStorage
You can use AsyncStorage to save the passing screen data locally on the user's device. Here's how:
- Import AsyncStorage from 'react-native'.
- Use AsyncStorage.setItem() method to save the passing screen data with a key.
- Use AsyncStorage.getItem() method to retrieve the passing screen data using the same key when the app is opened again.
import { AsyncStorage } from 'react-native';
// Save passing screen data
AsyncStorage.setItem('passingScreenData', JSON.stringify(passingScreenData));
// Retrieve passing screen data
AsyncStorage.getItem('passingScreenData').then(passingScreenData => {
if (passingScreenData !== null) {
// Do something with passing screen data
}
});
Method 2 - Using Redux
You can use Redux to save the passing screen data in a global state. Here's how:
- Create a Redux store and reducers for the passing screen data.
- Dispatch an action to update the passing screen data when the user passes the test.
- Use mapStateToProps() method to retrieve the passing screen data when the app is opened again.
// Define Redux store and reducers
const passingScreenReducer = (state = {}, action) => {
switch (action.type) {
case 'UPDATE_PASSING_SCREEN_DATA':
return { ...state, ...action.payload };
default:
return state;
}
};
const rootReducer = combineReducers({
passingScreen: passingScreenReducer,
});
const store = createStore(rootReducer);
// Dispatch action to update passing screen data
store.dispatch({ type: 'UPDATE_PASSING_SCREEN_DATA', payload: passingScreenData });
// Retrieve passing screen data
const mapStateToProps = state => {
return { passingScreenData: state.passingScreen };
};
These are just two methods to save passing screen data in React Native. Depending on your app's complexity and use case, you may need to use a combination of these methods or try other methods such as using SQLite or Firebase.
