The named parameter 'isInitialRoute' isn't defined.
I can't run my app because of this debug error. Can anyone help out. The named parameter 'isInitialRoute' isn't defined. Try correcting the name to an existing named parameter's name, or defining a named parameter with the name 'isInitialRoute'. This is the dart code that causes the error.

Looking at buying a new computer are AMD processors working well yet?
About a year ago I started working with a flutter developer who had the hardest time getting emulators through ANdroid Studio running well on their machine. I am looking to get a new computer and some of the AMD processor models are tempting for the price. Are things better now or is it still best to stick with Intel when using Android Studio & Flutter?

AR Applications in Flutter???
Good day Flutter Devs, I’m really new when it comes to developing mobile applications especially to the Flutter tool just wondering how good is the AR side of Flutter. A little guidance or views on what tools I should be using in order to accomplish my thesis project will do a lot of help to me, and down below is what I’m trying to accomplishObjectives:Develop an AR mobile app.One mobile platform that lets users switch between a Creator or Viewer user type.Creators that lets them simulate a location or space, and turning it into their own personal digital art hub gallery by being able to place their artworks in a digital format in their AR spaceViewers that lets them have an easy time locating any recent or existing creations created by the Creator using the application as well as being able to record a video of the ongoings within an AR space if the Creator allows it.For some reason I can't post images of what my UI's will look like so here's a link to see all the mockup UI's i've made https://docs.google.com/document/d/1x_ujLjg1TtBCFEnU9qXolvSFtvK4nkX6RjOs3pIcaDw/edit?usp=sharing

Online flutter editor that can load an entire project and comes with an Android emulator?
Author of (currently offline) Flutterpen here - I get requests to bring it back sometimes and like to ask people here what they think about having the editor back.Suppose I could offer you an online editor where you can work on your Flutter app from everywhere:Visual Studio Code in the browserAn integrated Android emulatorA working debuggerNo need to install Flutter Studio/android emulator yourselfImport/export zip filesHere's a screenshot of what this would look like.Would you pay 2 cents per minute to use it? No lock-in, use whenever you like.

Need help!
In my main page, I have two tabs, named tab 1 and tab 2. When switch to tab 2, it has an icon on upper right corner.When icon is clicked, it will open page C. I notice when I switch from tab 1 to tab2, it will call dispose in tab 1. When I switch from tab 2 to tab 1, tab2 dispose will be called.
