When trying to run flutter build web i get "build web" is not currently supported.
I had previous errors where i was stuck with Dart 2.5.0-dev.4.0.flutter-be66176534 and required 2.5.0 or higher, this has now been solved but i am unable to build my project.

I have tried
re-installing dart
re-installing flutter
re-installing Visual Studio code
copy file contents to a new web project (same error)
I couldn't find any information on what this is caused by and how to resolve it online
What can i do to resolve this error?
Please once do configure like below
flutter channel stable
flutter upgrade
flutter config --enable-web
cd into project directory
flutter create .
flutter run -d chrome
So currently you are at stable channel . You have to switch to the beta channel as flutter web is not at a stable channel right now. In order to make it working run the following commands in the terminal.
flutter channel beta
flutter upgrade
flutter config --enable-web.
After that restart your IDE and build the web app.
I was facing problem in flutter stable 2.0.2, by running
flutter create .
it was not creating web module, after upgrading it has started working. I guess my flutter web sdk had some issue so by fresh upgrade it got fixed.
if your are facing the problem
Ambiguous organization in existing files: {package_name1, package_name2}. The --org command line argument must be specified to recreate project.
you can use this command
flutter create --org package_name1 .
And
flutter run -d chrome
Just check whether you have used any plugins in pubspecs.yaml that is nonweb supportive.
you have to add web support to an existing app:
flutter create .
then try to
flutter build web

SOLUTION for this problem
I deleted the JDK 13. I installed JDK 8.
I gave the environment variable for the Flutter SDK. in user variables
flutter
C: \ flutter \ bin
I gave the environment variable for JAVA_HOME. in system variables
JAVA_HOME
C: \ Program Files \ Java \ jdk1.8.0_241
Then I accepted Android licenses with cmd.
(flutter doctor --android-licenses)
Now I can use flutter connectivity.
The problem is solved. Thank you.

I cannot debug or release to my app when I add Connectivity to my app's pubspec.yaml

You need to create a global file under your username in Mac. Just create a .bashprofile file as described bellow:
Open to see location and locate your flutter sdk inside.

Try to switch your flutter channel master to stable channel. After switching the channels you should call flutter upgrade to download the Flutter SDK and dependent packages.
Do this steps in the terminal
flutter channel stable
flutter upgrade
try to run your code after this steps.
Update to 1.9.1-hotfix4 fixed the problem
Your flutter doctor isn't showing any error as you had shared the commands.I think to share the run command terminal so that we can find out the stack of flowing of commands.
If you are getting error to build flutter project then you should update the Android Studio or VS Code Editor.
You can refer here:
Android studio-https://developer.android.com/studio
VS Code-https://code.visualstudio.com/Download
If you are able to create flutter project but doesn't getting run command then you need to update flutter and dart.
You can refer here:
Flutter-https://flutter.dev/docs/development/tools/sdk/releases
Dart-https://dart.dev/get-dart
If still you are suffering from error then you need to share some more Pics.
Probably something's gone wrong after you changed some files in of flutter ide. Also it does after updates crashed.
So the thing you should do is firstly backup your projects if it indeed. After backup remove the ide and be sure uninstalling complate succesful. Restart your computer and install all decencies again. Because sometimes upgrading does not works well to get good result.
P.S : Dont forget using flutter doctor for checking if any problem comes out.
A new installation of flutter/dart went smoothly without issue .. running "flutter doctor -v" gives the following output:

and yet attempting to run the defalut starter app "flutter/material.dart" results in ... "Unable to locate a development device; please run 'flutter doctor' for information about installing additional components" ... irrespective whether i use Intellij or Visual Studio.
However,

I have searched the web and found similar complaints .. but no solution. I was hoping that someone might be able to throw some light on this as I am sure it must be something simple and straight forward.
Visual Studio is a new installation but I have been using Intellij now for 6 months on a daily basis and rarely have issue with it .. especially one that i cannot fix. :)
Thank you in advance.
open Terminal in Android Studio or VS Code.
and writes this command :
flutter config --android-sdk <sdk-location>
SDK-location is your Path for SDK! for Example :
flutter config --android-sdk /home/sanaebadi/Pasport/programming/and_dev/sdk/sdk-tools-linux-3859397/
I had the same problem , then I tried this solution , and it helped me and my flutter app is running on my phone ..
all you need to do is install Android API level 29 (Android 9.0+ "Q")
go to Setting > Android SDK >SDK platform>Check Android 9+ and Press Apply button
I found this solution from github .. her is the link ..
Hope this help you

In Android Studio, ensure that the API level of your Project SDK (File->Project Structure) <= of the API level of your AVD.
I just getting with flutter. I have installed it along created a project successfully.
But when I try to run it fails.
Below is the output with flutter doctor -v

I have installed the Flutter extension.
I tried uninstall and install a couple of time, but still the same result.
I think there are two issues here:
Doctor says you don't have the extension
Your project doesn't run
1 Doctor says you don't have the extension
This is a bug I've just fixed. Seems like VS Code may have started lower-casing the extension folders recently, and our test for them was case sensitive. The fix is in master but hasn't made the beta channel (as of 22nd June 2018).
Note: This check doesn't affect anything else, as long as the extension is installed this is just an issue with the doctor output.
2. Your project doesn't run
This is probably not related to the doctor output if you can see the extension in VS Code. You haven't included any info on the reason your app doesn't run (does it give an error? what do you see?) so it's hard to guess; but if you can provide that info I can take a stab.
If you haven't already, it's also worth running the project from the command line with flutter run to see if it works there, to see whether the issue is specific to VS Code or something else with your setup.
If if works from the command line then I would recommend opening an issue on GitHub for the Dart-Code repo with more information and we can track it down from there.
Open your VS Code if you have it installed, if not you can still install it from the link. Flutter internally use Dart language to build a mobile app. So you need to install this extension
Then open this link "https://marketplace.visualstudio.com/items?itemName=Dart-Code.flutter" to install this extension.
After the installation run your flutter doctor -v to confirm.
I've installed flutter but when I run flutter doctor to verify the installation, I get:-
Android SDK is missing command line tools
I've doubled checked that the command lines are installed.
What do I need to do remove this error?
I've included the full flutter doctor -v output below:-

On Android Studio open SDK Manager.
Go to SDK Tools tab.
Check if Android SDK Command-line Tools is checked. If not, check and apply the changes.
For some reason, after updating flutter and Android Studio, I got this error too. Seems like some new requirement that for some reason wasn't automatically installed.
This fixed it for me.
I think ANDROID_HOME and ANDROID SDK should be pointing to the same path and that is the SDK's root directory.
In my .bashrc (on LINUX), following are
export ANDROID_HOME=/home/myname/Android/Sdk
export PATH=/home/myname/Android/Sdk:$PATH
export PATH=/home/myname/Android/Sdk/platform-tools:$PATH
export PATH=/home/myname/Android/Sdk/tools:$PATH
export PATH=/home/myname/Android/ndk-build:$PATH
Just solved the problem. Here are my system settings:
System variable ANDROID_SDK_ROOT points to my Android SDK dir
In system Path variable, I have sdk/tools, sdk/platform-tools, and /flutter-dir/bin
Also make sure you don't have dulplicated directories. I previously downloaded another platform-tools and add it to Path, so I had to delete it and use the sdk's one.
After changing those things, I close the flutter cmd windows and run flutter doctor on PowerShell. Worked like a charm!
Please download the latest sdk build-tools to solve the problem of Android SDK is missing command line tools
