Data parsing issue at android while using Flow path to create the same screen again

问题

I am playing around with square up android Motor & Flow library . I tried to pass the data from Screen A to Screen B and I am able to successfully retrieve data at Screen B . The problem araise while I try to call Screen B from Screen B (Re creation of same screen again).

Screen A

@Override
public Object createComponent(MainActivity.Component parent) {
    return DaggerScreenA_Component.builder().component(parent).fingerPrintModule(new FingerPrintModule()).moduleDependencies(new ModuleDependencies()).build();
}

@dagger.Component(dependencies = MainActivity.Component.class,modules = {ModuleDependencies.class, FingerPrintModule.class})
@DaggerScope(Component.class)
public interface Component extends AppDependencies {
void inject(ViewA view);

SharedPreferences sharedPreferences();

FingerprintManager fingerprintManager();

KeyguardManager keyguardManager();
}

@DaggerScope(Component.class)
public static class Presenter extends ViewPresenter<ViewA> {
    @Inject
    RestClient restClient;

@Inject
ResponseCache responseCache;

@Inject
SharedPreferences sharedPreferences;

@Inject
FingerprintManager fingerprintManager;

@Inject
KeyguardManager keyguardManager;

Context context;

public Callback<WeatherResponse> configServiceCallback = new Callback<WeatherResponse>() {
    @Override
    public void onResponse(Call<WeatherResponse> call, Response<WeatherResponse> response) {
        Log.d("ScreenA","Response data -->"+response.body().toString());
        responseCache.setWeatherResponse(response.body());
        Flow.get(context).setHistory(History.single(new ScreenB("Value Passed from previous Screen")), Flow.Direction.FORWARD);
    }

    @Override
    public void onFailure(Call<WeatherResponse> call, Throwable t) {

    }
};


private String errorMessage = "";

@Inject
Presenter() {
}

@Override
protected void onLoad(Bundle savedInstanceState) {
    super.onLoad(savedInstanceState);
    context = getView().getContext();
    Log.e("Screen A","shared preferences-->"+sharedPreferences.getBoolean("HARI",false));
    Log.e("Screen A","fingerprintManager-->"+fingerprintManager);

        restClient.getService(WeatherService.class).getConfiguration().enqueue(configServiceCallback);


}


}

Screen B:

private static String value = "";

public ScreenB(String value) {
    this.value = value;
}

@Override
public Object createComponent(MainActivity.Component parent) {
    return DaggerScreenB_Component.builder().component(parent).fingerPrintModule(new FingerPrintModule()).module(new Module()).build();
}

@dagger.Component(dependencies = MainActivity.Component.class,modules = {FingerPrintModule.class,Module.class})
@DaggerScope(Component.class)
public interface Component extends AppDependencies {

    void inject(ViewB view);

    FingerprintManager fingerprintManager();

    KeyguardManager keyguardManager();
}

@DaggerScope(Component.class)
public static class Presenter extends ViewPresenter<ViewB> {

Context context;

@Inject
FingerprintManager fingerprintManager;

private String errorMessage = "";

@Inject
ResponseCache responseCache;

String value = "";

@Inject
Presenter(String value) {
    this.value= value;
}

@Override
protected void onLoad(Bundle savedInstanceState) {
    super.onLoad(savedInstanceState);
    context = getView().getContext();
    Log.d("ScreenB","Entered Value-->"+value);
    getView().textView.setText(value);
}



 public void moveToNext(){
        Flow.get(context).setHistory(History.single(new ScreenB(getView().editText.getText().toString())), Flow.Direction.FORWARD);
    }


}

@dagger.Module
public static class Module {
@Provides
@DaggerScope(Component.class)
public String provideValue() {
    return value;
}

}

I have added this project it to Github also.Any one faced this issue ? Please share your comments and suggestions. Thanks in Advance.
