I am trying to automate flutter app using java and flutter finder. For each and every flutter element I am getting unknown locator

public class FlutterAutomation {

private static AndroidDriver driver;
private static final String appPath = "C:\\Users\\NMAHESHBABU\\flutterlogin-debug.apk";
private final String deviceName = "Pixel 3 API 29";
private final String testName = "Flutter Automation";

@BeforeTest
public void setUp() throws MalformedURLException {
    DesiredCapabilities flutterCapabilities = new DesiredCapabilities();
    flutterCapabilities.setCapability("deviceName", deviceName);
    flutterCapabilities.setCapability("platformName", "Android");
    flutterCapabilities.setCapability("automationName", "flutter");
    flutterCapabilities.setCapability("app", appPath);
    flutterCapabilities.setCapability("noReset", true);
    flutterCapabilities.setCapability("testName", testName);
    driver = new AndroidDriver(new URL("http://127.0.0.1:4723/wd/hub"), flutterCapabilities);
    System.out.println("Created AppiumDriver");
}

@Test
public void checkLoginFunction() throws InterruptedException {

    FlutterFinder find = new FlutterFinder(driver);
    Thread.sleep(3000);
    FlutterElement txt_username = find.byValueKey("txt_username"); // this is valid locator
    FlutterElement txt_password = find.byValueKey("txt_pass"); // this is not a valid locator actual locator is txt_password
    FlutterElement btn_click = find.byValueKey("button_login");// this is valid locator
    System.out.println(txt_username);
    System.out.println(txt_password);
    txt_username.sendKeys("user@gmail.com");
    txt_password.sendKeys("user123");
    btn_click.click();

}

@AfterTest
public void tearDown() {
    if (driver != null) {
        driver.quit();
    }
}

}
