    [H] Add ImageStreamCompleter.ha… (compare)

@Erinziyi This is happening due to null value in the text widget itself, So Try to wrap your data into a string like "$data", So that null values can be avoided in widget creation.
h ello
does the different isolate comunicate with port by use the socket?
does the port theory is used the local socket?
@Erinziyi Your body[statusMsg] is returing null, first, debug it and check why it is doing so, and also wrap it like a string so that it don't give an error as "${body[statusMsg]}" .
try it now
void _login() {
        .then((body) {
      if (body["status"] == "true"){

I am quite new to Flutter Google Maps Polyline. I wanted to draw multiple polylines to form a loop of directions. The problem is I can't set the polylines to be drawn into the street route because the Google Map Polyline plugin only allows a single origin and destination LatLng coordinates. Below are my codes:
routeCoordinates = await googleMapPolyline.getCoordinatesWithLocation(
          origin: LatLng(3.082519, 101.592201),
          destination: LatLng(3.082519, 101.592201),
          // LatLng(3.082097, 101.585165),
          mode: RouteMode.driving);
              polylineId: PolylineId('route1'),
              visible: true,
                LatLng(3.082519, 101.592201),
                LatLng(3.083355, 101.589653),
                LatLng(3.08171, 101.587507),
                LatLng(3.082519, 101.592201),
              width: 4,
              color: Colors.blue,
              startCap: Cap.roundCap,
              endCap: Cap.buttCap));
So far I've tried adding an array into points and it returns a loop but not as what i expected:-
Attached above is the preview of the output
Anyone knows if v1.12 is a bit stable. Currently using the latest stable version (v1.9) but the "sign in with Google" package requires atleast 1.10
Anyone knows why onAttachedToEngine is called twice in initialixzation plugin ?

I have issues with CircleAvatar.. I added 3 images to my assets folder and only one could display as a background image of the circleAvatar. I have tried searching on this problem, but i have not found any answer.. the two non- functioning pictures are greater than 2mb while the working picture is 153 kb.. So, i want to confirm if CircleAvatar has size limit for backgroundImages
@lordvidex To create fluid flutter applications , you would best try and limit the maximum size of images you display in Avatars and other widgets to say no more than 20k. My app allows for users to take pictures and the image is stored in Storage in a compressed format which is no more than 1.5k , lossy uncompressed max 12k around. It takes time to render images so best not to load from assets but cache in RAM also.

hello, anyone used branch sdk in flutter?
Tom Dowdell
I have just started with Flutter on Intellij. So far so good. My friend is also starting but he is using VSCode for Android. He said in addition to Dart he also has to use Kotlin to do SMS. If this is true I'm really confused. I thought you could do all coding in Dart. Thoughts?
@tomdowdell Flutter allows for multiplatform development with a single codebase, however - it may not provide every PLATFORM feature across both platforms in which case the architecture is open to allow you to write custom plugins to fit the void. Here you can therefore write native platforms in OBJc/Swift and Java/Kotlin to write a uniformed plugin 'aka' feature that will be used across your Flutter app. In the case of SMS - There are many good plugins that offer this immediately. So unless there is something very specific that your colleague is after that isnt offered in these plugins then I suspect he may be somewhat confused as to Flutters eco system ...
Tom Dowdell
Thanks @shenaz. Great explanation. Is it reasonable to assume that now or in the near future a developer could work exclusively on Flutter and Dart without need to work at native level for most common project types?
Also, is there an SMS plug-in you recommend?

We have an error with video player on android 9 (can't get data from net), so what is the solution?
Is it depended on network security ?
Have I create an XML file?

I'm looking for any tools to make flutter plugins easier/more reliable. Specifically, I was wondering if anyone's heard of a MethodChannel stub generator... something that would generate the boilerplate handler code for kotlin/swift (or java/objc)... seems like this would help greatly in ensuring that the data you're passing back and forth is structure correctly.
Randal L. Schwartz
there’s also a lot of boilerplate in wiring up the dart side to the “native side”, and I understand there are people working on that to make iteasier.
oh, may be talking of same thing.
What is the difference between running flutter packages get and pub get?
Randal L. Schwartz
pub get works from the current dart SDK
flutter packages get uses the pub in the flutter sdk
they may have differences
Randal L. Schwartz
And you should stay with the one you’re actually developing with @advonesix

@agreensh thanks! i am so stupid i dont realize like that.

is there any other components aside from material and cupertino?

Has anyone seen this error with the new multi platform support for url_launcher? can any one give me direction on how to correctly configure the latest in pubspec if i am only using ios and android?

Could not determine the dependencies of task ':app:transformClassesAndResourcesWithR8ForRelease'.

Could not resolve all task dependencies for configuration ':app:releaseRuntimeClasspath'.
Could not resolve project :url_launcher_macos.
Required by:
project :app > project :url_launcher
Unable to find a matching configuration of project :url_launcher_macos:

      - None of the consumable configurations have attributes.
Are there any active flutter contributors online? How do I get started with contributing to the flutter project? I've picked some minor issues, but I'm not sure how to really get into it and which issues to choose to work on.
( I know there are lots of different issue labels )
@tomdowdell Most Flutter developers do not need to look into Platform Channels or FFI as there are a host of ready made plugins that encompass platform features for both iOS/Android. With the advent of Desktop & Web & the planned Fuchsia OS - the strategy for google will be to extend their plugin architecture to easily support these and other future platforms. So to reiterate, unless you have a very specific platform feature not currently available in plugins with pub.dev then there is no need to delve into this area (i.e plugin development). With respect to SMS , I have used this plugin with great success https://pub.dev/packages/flutter_sms
