How to retrieve text value from RichText in flutter?

Question

Here's the Flutter code:

   Column(
              mainAxisAlignment: MainAxisAlignment.center,
              crossAxisAlignment: CrossAxisAlignment.start,
              children: <Widget>[
                Padding(
                  padding:
                      const EdgeInsets.only(bottom: LuminaSpacing.extraTiny),
                  child: RichText(
                    key: Key('last_updated'),
                    textAlign: TextAlign.end,
                    text: TextSpan(
                      text: '${_localize.last_updated}: ',
                      style: wldTheme.textTheme.display1,
                      children: <TextSpan>[
                        TextSpan(
                            text: '${settingStore.lastCheckinTime}',
                            style: wldTheme.textTheme.body1),
                      ],
                    ),
                  ),
                ),

I'm using appium with java to automate my test cases

Here's my code:

FlutterFinder ele = new FlutterFinder(driver);

System.out.println("Last update: "+ele.byValueKey("last_update"));
// System.out.println("Last update: "+ele.byValueKey("last_update").getText());  // It waits for long duration

The output I get is

Last update: [pro.truongsinh.appium_flutter.finder.FlutterElement@870fb657 -> unknown locator]

Solution

you need to create a controller like this: var textController = TextEditingController(); and aggregate the controller to your RichText widget, with this controller you can get the value of the text like this: textController.text

Please check, you are specifying Key and expecting element by ValueKey. Try passing ValueKey<String>('last_updated') instead of Key('last_updated').

already tried that way too but didn't work. Also tried using semantic label too.

controller is not defined for RichText.
