FATOS Developer Introduction
Component
You can find more in-depth explanation about our SDK at https://www.npmjs.com/package/react-native-fatos-sdk 
In this section, we will introduce a brief structure of the SDK interface.
1. Structure description of react native ui 
FatosMainView.js is the top-level main view. It is rendered in the order in which it is registered in the function render(). function are rendered in the order in which they are registered. Unnecessary views can be unregistered. You can unregister unnecessary views.
​
render() {
​
     return (
        <View style={styles.container}>
            {mapView}                // Map view
            {firstTbTView}           // TBT view
            {secondTbTView}          // TBT view
            {speedoMeterView}        // Speed view
            {RGView}                 // Map control view
            {SDIView}                // SDI view
            {bottomView}             // Bottom view
            {laneView}               // Lane information
            {searchView}             // Search view
            {searchListView}         // Search list view
            {routeSummaryView}       // Route summary view
            {summarySearchView}      // Route summary search view
            {summarySearchListView}  // Route summary search list view
            {webView}                // Web view
            {indicator}              // loading view
        </View>
