How would you make a top tab bar that only shows on one particular page?
I have an appBar with a bottomNavigationBar that takes you to a particular page. On one of the pages, I want to show a top TabBar, which can be used to swipe through different pages.So the basic structure of the app is like this:ScaffoldAppBarBody(the widget here changes depending on what's selected on the BottomNavigationBar)BottomNavigationBarSo I have one widget that is supposed to show when one of the buttons on the BottomNavigationBar is pressed.This is what I tried for that widget:

Widget build(BuildContext context) { return ListView( children: <Widget>[ DefaultTabController( length: 3, child: TabBar( tabs: <Widget>[ Tab(icon: Icon(Icons.directions_car)), Tab(icon: Icon(Icons.directions_transit)), Tab(icon: Icon(Icons.directions_bike)), ], ), ), Text("Another child under the tab bar") ], ); } 

However, the background of the TabBar is white, when my app's primary color is blue. Is this the best way to do this?Thanks.

I'm a React Native dev and would like to make a comprehensive comparison between Flutter and RN
tldr;I will try every feature that's needed for a production-ready app and need your opinions/support as well.​I've been developing mobile apps with React Native for 2+ years. I'm pretty confident I tried almost all platform capabilities including native modules (i.e. native bridge).I've read a lot of articles recently, Upon my research I can listPros:+ Performance is better than RN – startup time is faster, button tap is more responsive+ UI output is more identical across platforms+ Has a good CLI supportCons:- New language for almost all developers – no web dev, ios or android dev uses Dart by default- CPU usage is (generally) higher – Skia has its own implementation which lacks of platform-specific native optimizations- Has a small community which means limited extensions and support – I think this won't be an issue in near future​Besides the pros and cons above, I would like to try flutter and share my experimentations so I made a list of features that you will need for a production-ready app. I list them under 3 headings:UI: Just visual qualityNative: Native performance and accessing native featuresBusiness Logic: Managing global and local states, CRUD operations as well
​UIBuilding Pixel Perfect UI (Render of shadows, border-radius, color representation such as rgb, hsla, hex)Flex-box modelSafe Area ViewLine-height iOS vs AndroidImage styling (resizing and positioning)Text Input capacity (e.g. keyboard types, listening events)NativeCustom native module supportPush NotificationsIn-app PurchaseCapacity of Webview (Possible to listen every url and content)Websocket (socket.io) integrationApp size iOS vs androidPlaying Video/Audio filesAnimationsMapsBusiness LogicJSON encoding/decodingSeparation of stylingComplex navigations (nested tab and stacked screens)Handling HTTP requestsState management (BLoC vs Redux)Anything you want to add or think it's redundant? I'd like to hear your opinions as well.Also, I'm planning to write a post so I will definitely need your support on learning "flutter-way". Please share your contact info if you want to contribute.
ThanksPS: I've already seen this page

Any good guides for cross platform ui development?
I just started using flutter, and so far I love it. However, I had a question. How can I make a single UI that looks "natural" in both iOS and Android? I.e., I wouldn't want to make a standard material app and put it on iOS, but I wouldn't want to make two separate UIs. Any help/links to guides would be appreciated. Thanks in advance!

What would be a good reference app teaching best practices?
Is it a standard practice in Dart to keep several classes as part of the same file? I keep seeing many Flutter apps, where everything seems to have been crunched in a single file. What would be a good reference application to have a look at?

[Help] SpriteWidget Tutorials/walkthroughs?
Hi all,I'm keen to jump on the Flutter bandwagon and have followed a few tutorials to get the basics down. While looking around, I discovered SpriteWidget, which could be used as a game engine.https://pub.dartlang.org/packages/spritewidget#-example-tab-I was attempting to create my own little game, using the space blast example here:Https://github.com/spritewidget/spaceblastBut I'm really struggling to get anything going. Ive googled, but there seems to be very little info out there on SpriteWidget beyond these few examples I've found. I was wondering if anyone knew of any resources that really walks you through what parts do, how best to layout code. I've tried to follow step by step how the space blast game works but am finding it very difficult. Any assistance would be greatly received. I wish I could write up some blog tutorials for this as I think it's really needed but have utterly failed.
