 Use `Provider` to wrap what you return from your root component's render method:

+</Provider>
+```
+
+</TabItem>
+<TabItem value="dynamic" label="Dynamic" default>
+
 ```js
 <Provider myObject={this.myObject}>
   <NavigationContainer>{/* Screen configuration */}</NavigationContainer>
 </Provider>
 ```
 
+</TabItem>
+</Tabs>

 this will allow you to access `myObject` from any React component in the application through the `inject` function which can be quite useful.
 
 Use `observer` function to wrap all components that render observable data. This will make sure the components re-render once the data they render changes.
