[Python] Get text value from Flutter Widget using Appium Flutter Driver

I want to use Appium under Python with the Appium Flutter driver to test my Flutter application. Some things are already working, but I have a problem with the text widgets.

I can locate a text element using the semanticsLable (see code), but then it is not possible to read the text value from the FlutterElement. Am I doing something wrong here or does it just not work this way?

Flutter code:

const Text("Text with semanticsLable", semanticsLabel: "text_semantic_lable"),


Python code:

driver = Remote('http://127.0.0.1:4723',
{'platformName': 'android',
'automationName': 'flutter',
'platformVersion': '',
'deviceName': 'emulator-5554',
'app': '/Users/xxxx/AndroidStudioProjects/hello_world_appium/build/app/outputs/flutter-apk/app-debug.apk'
})

finder = FlutterFinder()
text_finder = finder.by_semantics_label("text_semantic_lable")
text_element = FlutterElement(driver, text_finder)
print(text_element.text)


Error log:
