how we can handle Flutter: wait for drop down list

public void selectRandomCustomerCategory() {
try {
// Step 1: Click the dropdown
FlutterElement categoryDropdown = flutterFinder
.byValueKey(TestKeys.customerCreateEditPageTestKeys.category);
categoryDropdown.click();
logger.info("Category dropdown clicked");

		// Step 2: Define possible categories
		String[] categories = { "Manager", "Founder" };

		// Step 3: Randomly choose one
		String chosen = categories[new Random().nextInt(categories.length)];
		String key = "customer_create_edit_page_category_" + capitalize(chosen);

		logger.info("Randomly selecting category: {}", key);

		// Step 4: Click the selected category directly
		FlutterElement selectedElement = flutterFinder.byValueKey(key);
		selectedElement.click();

		logger.info("Category selected: {}", key);

	} catch (Exception e) {
		logger.error("Failed to select random customer category", e);
	}
}

Just the element is staying on, waiting for a long time. How can we use the drop-down selection in Flutter

Start with the selectRandomCustomerCategory() entry point and the FlutterDriver click calls shown in the log, especially the second click on customer_create_edit_page_category_Founder. Reproduce the dropdown interaction and determine why the selected element remains waiting; done means a category selection completes without the element hanging.
