StacDynamicView class

A Stac model for dynamically fetching data and rendering it using a template.

This widget makes a network request based on the request configuration. The fetched data, potentially targeted by targetPath, is then used to render the template. The full response can be stored in the Stac context using resultTarget. It also supports custom widgets for loaderWidget, emptyTemplate (if data is empty), and errorWidget states.

StacDynamicView(
  request: StacNetworkRequest(url: 'https://api.example.com/data'),
  template: StacText(data: 'Name: \${data.name}'), // Example: template uses data binding
  targetPath: 'items', // Path to the list within the response
  resultTarget: 'apiData', // Where to store the full response in context
  loaderWidget: StacCircularProgressIndicator(),
  emptyTemplate: StacText(data: 'No items found.'),
)
