TWSViewCustomTabsExample
Demonstrates how to use TWSView with custom properties (props) defined in the TWSSnippet. The props field in the TWSSnippet allows you to attach custom metadata to a snippet in JSON format. These properties can be used for various purposes, such as configuring the behavior of your app or providing additional context to your view.
In this example, we access the custom tabName property (if it exists) and display it using a Text composable. The props can include values of any type, including classes, allowing you to extend the functionality of the snippet with complex data structures.
This flexibility allows you to pass any additional information your app might need to handle the snippet.
Working example can be found here. Download the Sample app from our web page to explore this functionality interactively.
Hint: try changing tabName or tabIcon on customTabs snippet and observe changes in the app instantly.
