I'm trying to run my first flutter code on the web. I followed setup instructions provided in Building a web application with Flutter and created a very simple app, that's only supposed to display a navigation bar. Now as I'm running my application for the first time on "Chrome (web)" device, it won't connect to the browser. It's been almost 20 minutes and it's still telling me "Attempting to connect to browser instance".
> flutter run -d chrome
Launching lib\main.dart on Chrome in debug mode...
Building application for the web... 1215.1s
Attempting to connect to browser instance..
(This is taking an unexpectedly long time.)
Can anyone guide me on how to fix this?
In my case, I couldn't disable the virus guard. So I used the server mode.
flutter run -d web-server
Launching lib\main.dart on Web Server in debug mode...
Building application for the web... 8.8s
lib\main.dart is being served at http://localhost:57598/
Then go to the URL shown.
The same thing happened to me, I disabled the anti virus and it worked
It's mostly nothing to do with Flutter but, it's either because you have logged in your computer in safe mode. In my case the shift key was stuck and I had no idea I was in safe mode.
Or else You need to check your firewall, go to System Preferences > Security and Privacy > Firewall --click the lock below and enter your system password -- and then click firewall option -- In there add your editor to allow internet connection for android studio Or VS Code.
I experienced the something similar, chrome opens but never showed the web app (just white screen). In my case it had to do with the interaction of flutter and riverpod.
If you are using riverpod 1.0.0 and flutter 2.5.3 you need to update flutter to 2.8.0 or 2.8.1 (see this issue: https://github.com/rrousselGit/river_pod/issues/889)

I just started-off with flutter web and I want to use brave browser to debug my flutter apps not chrome or edge.
When I use flutter devices command, it gives the following result.
No devices detected.
Run "flutter emulators" to list and start any available device emulators.
I'm using brave by using the link provided by web-server and it does not support hot reload.
So, how to configure browsers other than chrome or edge with flutter web for complete functionality.
I found this:
All you have to do, based on your Linux operating system (for Windows
and macOS the process is similar), is to modify your .bashrc file and
insert this line:
#Put your Brave installation location here
export CHROME_EXECUTABLE="/opt/brave.com/brave/brave-browser"
For MacOs,
export CHROME_EXECUTABLE="/Applications/Brave Browser.app/Contents/MacOS/Brave Browser"
You can use flutter run -d web-server to run your app like a server.
This means that you can just enter the URL on any browser of your choice to access your Flutter app !
Drawbacks:
Hot Restart/Reload from the terminal is not possible. You must refresh the page on your browser instead.
Advantages:
You can use any browser for developing flutter apps.
You can even use ngrok to forward your port to a HTTPS URL, and access your flutter app from anywhere (your phone, your desktop , someone else's device etc.)
PS: Credits to the Issue #77229 for helping me find this solution. I am aware that this workaround has already been suggested on this thread.
I just wanted to put out a simpler answer for the general viewer.
I've been diving in the same issue, it's known Brave it's Chromium-based, this will help u https://github.com/flutter/flutter/issues/77229
I tried creating a new flutter project in Visual Studio Code, but for whatever reason it now has a default device of Google Chrome every time I try to run it. I don't want to run Flutter in web environments whatsoever: is there any way I can disable this?
Run the following command to disable web completely.
flutter config --no-enable-web
Then restart your editor if necessary.
First, run your emulator from the AVD manager or connect your physical device while it's on debugging mode, if it's an android device, then choose the device you want to run from the flutter device selection option
Hey Im trying to Remote debug an Ionic Application, it was working recently, but now the device shows on Chrome Remote devices but when i click the device the app process wont show. it will show other mobile chrome tab Processes but not the Ionic app.
any clues ?
I fixed this, It was my fault, I built a release apk and was expecting a debug mode. When you build without the --release, It works
I need to troubleshoot an issue happening in a webview running within my app. This issue only occurs on Android versions lower or equal to 4.3. My app requires an up to date version of Google Play services.
In order to troubleshoot my webview, I usually can run my app under the Android Emulator (with the latest version of Android), then connect to the web view via Chrome (using chrome://inspect) - the web view appears in Chrome and I'm able to browse the DOM and debug.
To run the app under 4.3, I've created (under AVD) a new device from an existing device definition,
then picked the target Google APIs (Google Inc.) - API Level 18. I've then installed my app, but when trying to run it, I get the error message "This app won't run unless you update Google Play services.". There's an "Update" button on the previous dialog, but nothing happen when clicking on it.
I then tried to debug my issue using Genymotion. I've created a device under 4.3, followed these instructions to flash my device with the latest Google Play services and installed my app. I can now run the app and reproduce the issue within this simulated environment.
The trick now is to be able to connect to the web view from my local Chrome browser. I've enabled remote debugging as described here. Now my device appears in Chrome, but the web view is not showing up in the inspector. Similarly, if I open a new tab under the native browser, it won't show up in the remote inspector. If I open a new tab under Android Chrome though, I can see it showing up under my remote Chrome inspector.
I can see two way moving forward and successfully accessing to the DOM of my webview:
Fixing the "Update" issue under the Android Emulator running 4.3
Or
Connecting to my web view from my Chrome inspector while running the app under Genymotion
Any idea on how to solve one of these two problems?
I have been using weinre for sometimes. it's a pretty good tool to debug webview for android 4.3 and lower. It provides almost same interface as chrome debugger.
All you need to do are:
Install weinre
sudo npm -g install weinre
Client side:
Insert the following code to your webpage <head> section.
Note: it's better to put it at end of <head> section, otherwise there will be some strange errors and debugger won't show up.
<script src="http://<your server ip here>:8081/target/target-script-min.js"></script>
Server side
weinre --boundHost -all- --httpPort 8081
Debugger
open the debugger tool from weinre from your desktop browser:
http://localhost:8081/client/
Finally,
select any target in Targets part and then start debugging.
Remote debugging web views only works on devices with android 4.4 and above.
have a look at this :

I want to package and launch my BlackBerry Hello World application for WebWorks. For developement, I am using the Ripple emulator. The Ripple simulator says:
The build and deploy services are not currently running, would you like to start them?
After pressing the button Start Services nothing happens and no errors are in the error console.and i also did below steps as i have searched and get this result:
There are two reasons this might be happening. The first is that Chrome is preventing this from happening.
Open the Tools --> Extensions screen in Chrome
Enable 'Developer Mode' checkbox if it isn't already
Are you running Chrome in Incognito mode? If so enable the 'Allow in Incognito' checkbox
The other options is that nodejs is being blocked. If you're on windows, I'd suggest making sure that all user permissisons are enabled to allow you to run Chrome in a way that it can launch external processes.
And After doing all when ever i refresh page it says
The build and deploy services are currently running at localhost:9910. and after loading that page this message not visible but
The build and deploy services are not currently running, would you like to start them? message still there! please explain what's wrong here?
Thanks
This issue is solved by removing Ripple extension version 0.9.15 and installing version 0.9.16 (latest as of this posting), and restarting Chrome. When you click the 'Start Services' button, the console should appear displaying a build service start up message.

Install the latest beta and it should work!
