navigator

I'm fairly new to React Native, but I have a simple working app with three scenes. I was previously using Navigator but it felt laggy and was excited to try out React Navigation (as in https://reactnavigation.org/ ). After implementing React Navigation, my background color switched from white to grey, and what was grey to white. This is a strange and shouldn't be related. However I didn't change my styles. I only implemented the new navigation and the colors changed. When I revert back to Navigator my colors return. I'm using StackNavigator. Has anyone else encountered this strange phenomenon?

Firefox has launched a feature called Tracking protection in v42.0. It blocks several tracking scripts such as Google Analytics, Marketo, LinkedIn, etc. I was trying to detect it through navigator.DoNotTrack , but it returns unspecified in both cases – browsing in regular mode, and browsing in private mode – using Firefox 42.0 on Mac.

It does not tell if tracking protection , which

In iOS, we have a UITabBarController which stays permanently at the bottom of the screen when we push to a new ViewController. In Flutter, we have a bottomNavigationBar of a Scaffold. However, unlike iOS, when we Navigator.push to a new screen, this bottomNavigationBar disappears. In my app, I want to fulfil this requirement: Home screen has a bottomNavigationBar with 2 items ( a & b ) presenting screen A & B . By default, screen A is displayed. Inside screen A , there is a button. Tap that button, Navigator.push to screen C . Now in screen C , we can still see the bottomNavigationBar . Tap

I'm implementing an authentication flow in my Flutter app. After a sign in attempt, the CheckAuth (which checks whether a user is signed in or not and then opens home screen or sign up screen accordingly) is opened with this code: void _signIn() async { await _auth .signInWithEmailAndPassword( email: _userEmail.trim(), password: _userPassword.trim()) .then((task) { // go to home screen if (task.getIdToken() != null) { setState(() { Navigator.pushReplacement( context, new MaterialPageRoute( builder: (BuildContext context) => new CheckAuth())); }); } else { print("Authentication failed"); } });

What are the exact differences between project explorer, package explorer and navigator in eclipse? I am so confused of using the three. Because all seem to fit the same purpose. I don't know, what the exact difference is. Could anyone explain this to me and suggest which one is better for checking out? s.d From the Eclipse Documentation about the Common Navigator Framework : There are currently 3 major navigators in the Eclipse IDE. Project Explorer - This is an instance of the CommonNavigator that is provided by the org.eclipse.ui.navigator.resources plugin. It provides a view of the
