I'm trying to build in production mode my flutter app for web, but I have my "main.dart" file not in the root lib directory, this cause to not be able to build my app for web, I have tried to point the path to where the "main.dart" file is, like:
flutter build web path/to/my/main/file/main.dart --release
But ended out with an error message like:

This command works when you try to build an APK, but not to build a flutter web app.
Can somebody please tell me how to solve this?
add -t before your main.dart path.
eg.
flutter build web -t lib/main-dev.dart
I have a react application that was created with create-react-app and is using react-scripts version 3.4.2. The app works great but when I run eslint against it I get many invalid no-unused-vars errors. By invalid I mean that when I go to the file that variable is actually being used.
Based on this answer it seems the issue is related to #typescript-eslint/parser and #typescript-eslint/eslint-plugin. So I went ahead and executed npm list #typescript-eslint/parser #typescript-eslint/eslint-plugin on my app and this is what I get:
myapp#0.1.0 /Users/diego/myapp/client
└─┬ react-scripts#3.4.2
├─┬ #typescript-eslint/eslint-plugin#2.34.0
│ └── #typescript-eslint/parser#2.34.0 deduped
├── #typescript-eslint/parser#2.34.0
└─┬ eslint-config-react-app#5.2.1
├── #typescript-eslint/eslint-plugin#2.34.0 deduped
└── #typescript-eslint/parser#2.34.0 deduped
As seen all occurrences of the two potentially conflictive libraries are included by react-scripts app and that is why I am trying to update it.
I tried updating to 4.0.3 and when I do that eslint starts to work fine (those incorrect no-unused-vars are gone) but my app is unresponsive (I click on different buttons and/or links and nothing happen). The only error I see in the console after the update is this one:
Uncaught ReferenceError: process is not defined

at Object.8048 (<anonymous>:2:9496)
at r (<anonymous>:2:306599)
at Object.8641 (<anonymous>:2:1379)
I was searching this error and I found this question. The error is the same maybe not what the developer describes but reading through the answers I see many of them point to react-scripts as the root cause and that maches my scenario.
I tried some of the solutions in that question, in particular method 1 from this answer (I did not try method 2 because I am not sure if adding craco is what I want) and the solution from this other answer too but they do not work.
I also tried updating to react-scripts version 5 but I get A LOT of errors.
Is someone facing this issue or at least has some clue that could help me?
Thanks in advance.
The error message that you shared seems to be related to a bug with react-error-overlay.
react-scripts 4.0.3. uses react-error-overlay 6.0.9. However, 6.0.10 is marked as a patch, so npm uses 6.0.10 instead of 6.0.9, but 6.0.10 is not compatible with 6.0.9.
On the other hand, react-scripts 5 does not use react-error-overlay, but might be causing breaking changes with your other packages, hence the other errors.
You can find more information about the react-error-overlay bug in these issues on the CRA repository:
Hot Reload Fails, DOM adds an additional iframe containing entire
contents of the html DOM element #11880
Is this the bug of react-error-overlay? #11773
v5 Regression react-error-overlay build - Uncaught ReferenceError:
process is not defined #11771
Here's a possible solution with react-scripts 4.0.3.:
In your project's package.json file:
In dependencies, set the react-scripts version to 4.0.3.
Under dependencies, in resolutions, add react-error-overlay 6.0.9.
In devDependencies, add react-error-overlay 6.0.9.
"dependencies": {
...
"react-scripts": "4.0.3",
...
},
"resolutions": {
"react-error-overlay": "6.0.9"
},
...
"devDependencies": {
...
"react-error-overlay": "6.0.9",
...
}
Delete your project's node_modules folder and package-lock.json file.
Run npm install.
Run npm install react-error-overlay#6.0.9.

I installed the Dart SDK to run the above web app. The environment is Debian. Then I migrated to the folder /dart-comics-your_first_dart_app and did a "pub install" and got the following output.
pub install
pubspec.yaml has no lower-bound SDK constraint.
You should edit pubspec.yaml to contain an SDK constraint:
environment:
sdk: '>=2.10.0 <3.0.0'
See https://dart.dev/go/sdk-constraint
And after that, I changed the contents of pubspec.yaml as follows, and got the following error. How can I run it?
name: Dart Comics
dependencies:
dirty: any
uuid: any
json: any
environment:
sdk: '>=2.10.0 <3.0.0'
pub install
Error on line 1, column 7 of pubspec.yaml: "name" field must be a valid Dart identifier.
╷
1 │ name: Dart Comics
│ ^^^^^^^^^^^
╵
Use like this :
"name: Dart_Comics"
Just using _ will solve this issue.
I have recently installed Titanium Studio. Upon opening the program i get the error
"An internal error occurred during: "Computing SDK Info...".
java.lang.NullPointerException"
If i attempt to create a new emulator i get the error:
"An internal error occurred during: "Refreshing provisioning information...".
java.lang.NullPointerException"
Ive seen this question a million times but I cant get anything to work. I uninstalled and reinstalled node. I heard Titanium Studio wasnt working with node v12 so i went back to 0.10. I uninstalled and reinstalled java i reinstalled the java sdk i re installed the android sdk, i have attempted to "sudo npm install titanium -g" about 50 times and it always returns

I have tried deleting my config.json file and letting Titanium recreate it and setting the properties in the cli but absolutely nothing changes these errors. I am really at my wits end here. I really really need some kind of help so if anybody please knows how to just make Titanium Studio work I would be so grateful, Ive been trying for days...
Did you actually downgrade Node correctly? In your log above I see:
✓ node up-to-date (v0.12.0)
(Should be 0.10.35)
Have you tried running titanium sdk select [version] ?
My ISP in India has decieded to block Github for some reason.I have been trying to install Package Control for Sublime Text 3 both manually and use the Sublime Text 3 Console.In both of the cases,one dependency seems to be missing:
Package Control: Installing 1 missing dependencies
Package Control: Attempting to use Urllib downloader due to WinINet error: Error downloading package. Host not found (errno 12007) during HTTP write phase of downloading https://codeload.github.com/codexns/sublime-bz2/zip/1.0.0.
Package Control: Error downloading package. URL error [Errno 11004] getaddrinfo failed downloading https://codeload.github.com/codexns/sublime-bz2/zip/1.0.0.
error: Package Control
Unable to download bz2. Please view the console for more details.
Package Control: Skipping automatic upgrade, last run at 2015-01-03 11:32:25, next run at 2015-01-03 12:32:25 or after
I have downloaded the Sublime bz2 file manually,what should I do now?
EDIT:
Some skimming through stuff tells me that Package Control 3.0 has dependencies:
Once the package is extracted, a custom-generated python file is added to a special package named
0_package_control_loader. For Sublime Text 3, this is a .sublime-package file, whereas for
Sublime Text 2 it is just a folder. The reason for the name (and creating it as a .sublime-
package file in ST3) is to ensure it is the very first non-default package that Sublime Text
loads.
Is there a version of 0_package_control_loader.sublime-package that I can add manually(given that I have already installed Package Control with this dependency missing?
I've met the same problem as you. Below is the way I resolved it.
Try to get the file "sublime-bz2-1.0.0.zip". (It seems you have done it);
unzip it to the dictory "...\Application Data\Sublime Text 3\Packages\" and rename the sub-dictory name to "bz2".
open a new txt file and paste below code to it
{"platforms": ["*"], "url": "https://github.com/codexns/sublime-bz2/issues";, "version": "1.0.0", "description": "Python bz2 module", "sublime_text": "*"}
save the file to /bz2 and rename its file name as "dependency-metadata.json"
After done these, the hierarchy should be like this:
/Package
├─/bz2
│ ├─/st2_linux_x32
│ ├─/st2_linux_x64
│ ├─/st2_windows_x32
│ ├─/st2_windows_x64
│ ├─/st3_linux_x32
│ ├─/st3_linux_x64
│ ├─/st3_osx_x64
│ ├─/st3_windows_x32
│ ├─/st3_windows_x64
│ └─dependency-metadata.json
└─/User
├─/c2u_tmp
└─/Package Control.cache
restart sublime text3.
Hope it helps!

This worked for me, see: #godzig's answer, on this related Github issue: issues/989. The gist of it being:
open the 0_package_control_loader.sublime-package archive, in Installed Packages, of your SBT3 folder. Change the filename from 02-bz2.py to 01-bz2.py, and the error is gone; at least in my case anyway.
HTH
I got the same problem and I try and fix it by use manual installation like this:
Manual
If for some reason the console installation instructions do not work for you (such as having a proxy on your network), perform the following steps to manually install Package Control:
Click the Preferences > Browse Packages… menu
Browse up a folder and then into the Installed Packages/ folder
Download Package Control.sublime-package and copy it into the Installed Packages/ directory
Restart Sublime Text
Until your ISP unblocks Github (who does that?), you can download 0_package_control_loader.sublime-package here. I don't know if there are differences in the package for different versions of Windows, but this is from ST3 on Win8. Hope it helps!
Machael Lv's answer didn't help for me.
Then i just started sublime text as administrator for one time and problem dissapeared - now i can run sbt as ussual and error message doesn't appear again.
