React Native By Example

Custom RenderRow example

Let's look at how I created this component:

// Tasks/app/components/TasksList/index.js ... import TasksListCell from '../TasksListCell'; ... export default class TasksList extends Component {   ...   async _addTask () {     const singleTask = {       completed: false,       text: this.state.text     } 

Firstly, tasks are now represented as objects within the array. This allows us to add properties to each task, such as its completed state, and leaves room for future additions.

    const listOfTasks = [...this.state.listOfTasks, singleTask];     await AsyncStorage.setItem('listOfTasks',     JSON.stringify(listOfTasks));     this._updateList();   }   ...   _renderRowData (rowData, rowID) {     return (       <TasksListCell  completed={ rowData.completed } ...
