How to get text of the child element?

[Harsha-Gelato]

Hi Team,
I am using appium flutter driver, can someone please tell me how can I get text from the child element?

My current code is:
await driver.execute('flutter:waitFor', find.byValueKey(line_graph));

    btn = find.descendant({
        of: find.byValueKey('line_graph'),
        matching: find.byValueKey('test'),
        matchRoot: false,
        firstMatchOnly: true,
    });
    await driver.execute('flutter:waitFor', btn);
    const firstdate: string = await driver.getElementText(btn);

console.log(firstdate);

Error:

strong textCode of key:

@KazuCocoa Could you please tell me what is the best way I can print full output of getRenderTree command in some file because the output is too long and when I run this command in my script, half of the output gets skipped due to which I cannot share you the full output?

I think you can just write the entire string response in a file like https://www.geeksforgeeks.org/writing-to-file-in-python/ in the client side

line_graph had nested element with line_graph key. I'm not so familiar with the app structure, but I wonder if it needs to tune key somehow to reduce nest between line_graph and test, for example...
