Web app not opening on the chrome while debug #172348
Description
Steps to reproduce
I attempted to run my Flutter web project using the command:
flutter run -d chrome --web-port=6123 --web-browser-flag="--disable-web-security" --web-browser-flag="--user-data-dir=~/chrome_dev".
Upon execution, Chrome launches automatically, and four tabs open, each trying to load the Flutter project. However, after a short time, the terminal throws an error stating: “Failed to launch browser after 3 tries,” followed by the full launch command it attempted. The error suggests ensuring that Chrome is up to date and recommends using the -d web-server flag if the issue persists. Despite Chrome opening, it fails to load the project, and the Flutter tool eventually gives up trying to connect. This issue seems related either to the custom flags or Chrome’s inability to handle multiple simultaneous tab launches in this configuration.
Actual results
Failed to launch browser after 3 tries. Command used to launch it: C:\Program Files\Google\Chrome\Application\chrome.exe
--user-data-dir=C:\Users\Apoorva\AppData\Local\Temp\flutter_tools.f000e587\flutter_tools_chrome_device.7f799c7f --remote-debugging-port=58362 --disable-background-timer-throttling --disable-extensions --disable-popup-blocking
--bwsi --no-first-run --no-default-browser-check --disable-default-apps --disable-translate http://127.0.0.1:8080
Failed to launch browser. Make sure you are using an up-to-date Chrome or Edge. Otherwise, consider using -d web-server instead and filing an issue at https://github.com/flutter/flutter/issues.
