Dart Devtools not working after update.

[azad47808]

This morning when I run Devtools I got an updating message and after update DevTools opened but shows nothing.
this is my Devtools URL = http://127.0.0.1:9100/#?hide=debugger&ide=VSCode&theme=dark&uri=http%3A%2F%2F127.0.0.1%3A49683%2F7P9jVJjp0SU%3D%2F&page=inspector

My Flutter version is 1.19.0-4.1.pre
My Dart version is 2.9.0 (build 2.9.0-14.1.beta).

How are you starting DevTools - from the command line, VS Code, IntelliJ?

[bleonard252]

According to the link, VSCode. I'm experiencing the same thing running from the command line.

Another exception was thrown: Instance of 'minified:il<void>'

is being logged a lot.

From VS Code.

I have the same problem with the same configurations (Flutter 1.19.0-4.2.pre, Dart 2.9, VS Code 1.46.1) after recent update DevTools.
Also, it doesn't work from Android Studio 4.0 too. Both on Linux Debian 9.11.
What happened?

Same problem over here too. Tons of recurring exceptions:
"Another exception was thrown: Instance of 'minified:im'" Could not load content for org-dartlang-sdk:///lib/_internal/js_runtime/lib/js_primitives.dart (HTTP error: status code 404, net::ERR_UNKNOWN_URL_SCHEME).

The app works perfectly fine in vs code on the device.

Can I downgrade Dart Devtools? because it happens after the update.

Can you open DevTools from CLI? flutter pub global activate devtools; devtools

Trying to narrow this down to determine if the issue is specific to launching from VS code. Thanks.

From this comment above it sounds like this may occur from Android Studio too.

Could it be caching from the old version? Does pressing Ctrl+R in the browser make any difference for those seeing this?

No, I haven't used DevTools in Chrome yet. I tried with Firefox and that didn't work (Firefox error).

I used these two commands but not worked it's just a white page.

1: flutter pub global activate devtools
2: flutter pub global run devtools

I used this command before and now - still white page. (at http://127.0.0.1:9100)
Both from VS Code and Android Studio.
In Android Studio I can use embedded Flutter tabs - Inspector, Outline, Performance. And that's it.

A couple things to try:

• make sure you are using the latest version of Chrome
• clear your browser cache

Are you running from Mac, Linux, or Windows?

[ezbella]

I have the latest Chrome version, specially downloaded for the occasion. I've tried everything you suggested with no luck El mar., 7 de jul. de 2020 12:30 PM, Kenzie Schmoll < notifications@github.com> escribió:

Try appending '/#/' to the end of the url so that the url looks like http://127.0.0.1:9100/#/. The redirect is supposed to happen automatically.
