when I am in debug mode, it's just working fine, but after app build, Google fonts is not working on the mobile, the app is using the regular font.
I checked and did all available steps to solve the issue,yet I failed!
Steps I did:
In my pubspec.yaml file, I added dependencies as instruction and added import 'package:google_fonts/google_fonts.dart'; in every file.Then I ran the "$flutter pub get" Command,then I restarted the IDE, when it returned the same result, then I did the whole procedure with the PC restart, but nothing changed.
I checked the android manifest file, and the line <uses-permission android:name="android.permission.INTERNET"/> is already there.
Switched the IDE VS code to android studio, still not working.
I deleted every related file from mobile, and restarted the mobile, i did a "Clean installation(?!)" with internet connection, but no joy!
Is there any way to solve the issue?
You need to download the font files from fonts.google.com and place them in a directory in top level directory of your application.
Also configure them jn pubspec.yaml as assets.
Follow the steps mentions here
https://pub.dev/packages/google_fonts

I tried to run the basic click counter app in VSCode, but it is not working on emulator, or my physical device either.
These are the errors being thrown.
I have not changed any file from creation of project.
So I just won a new laptop in a competition and now I am having some trouble migrating my flutter projects. I have set up the editor and migrated the important files in the code, i.e the lib, image, font, pubspec.yaml and web. But this app is now throwing the following error
Launching lib\main.dart on Chrome in debug mode...
Waiting for connection from debug service on Chrome...
ERROR - 2020-12-29 13:08:07.845202
GET /main_module.bootstrap.js
Error thrown by handler.
AbsoluteImportUriError: 'file:///C:/FlutterProjects/xspectre/lib/help/Auth.dart'
package:dwds/src/debugging/metadata/provider.dart 154:9 MetadataProvider._addMetadata
package:dwds/src/debugging/metadata/provider.dart 133:15 MetadataProvider._initialize.<fn>
I thought it may be a problem with my flutter but it runs the default flutter app without problem.
I also tried deleting the file but the problem just shifts to another file. I can safely say that this a is a problem with the help folder which provides me essential tools such as the auth service. What should I do? I will provide any code neccesary. You can find the entire code here
The Error:
The error is happening because when importing your new project, some imports in your .dart files are now using absolute paths instead of relative paths. In your case, this is happening at least in one .dart file that is calling your Auth.dart.
Sloution:
Step 1: Look at the top of all your .dart files, more precisely at every single import. You will have to change everything starting with:
import 'file:///C:/...
by
import 'package:... and add the name of your app
Step 2: Rerun your project and everything should work now
If still issues, then make sure you looked at all your files to ensure you did not miss other wrong import... also, you can run flutter clean then run a Pub Get

I have been having issues with installing this package https://pub.dev/packages/graphql_flutter/install one of it's dependencies is this graphql package https://pub.dev/packages/graphql. When i do pub get it installs en shows everything expect for the graphql package in the dart packages folders. I have tried to install the graphql package separately but the package still doesnt show up than. And the import still gives the error "Target of URI doesn't exist: 'package:graphql/client.dart'." But it does show up in flutter/.pub-cache/hosted/pub.dartlang.org so i dont understand why it doesnt show in my project. I have tried using flutter clean, flutter clean pub cache and androidstudio's invalidate caches/restart function to no avail. I have also tried restarting android studio and my pc multiple times. I have also tried it with androidstudio run as admin.
This is my pubspec.yaml
this is part of my Dart packages folder as you can see it does not show
And this is the pub.dartlang.org folder on my pc
It ended up getting randomly fixed after 3 days. I just started android studio up and tried it again and suddenly it worked. No idea what fixed it in the end
Seen this issue a few times. Open Task manager in windows and check for adb.exe. There should be one copy running. I had 2 copies so removed 1 and restarted the other.
right-click --> end task for both.
All ok then.
Reloading VS code worked for me..
Reloading can be done ---> Command + R for Mac.
flutter application is not created even after the android and flutter plugin installation setup.
I have followed the following steps as given in the link
Flutter Installatioon steps
I dont know where I went wrong,. which installation steps I have missed.
My system is windows 32 bit.
I am encllosing the required screen shotsError screenshot

User Variable. path
Pleasee help me by fixing this issue
Try using Git instead of command line (cmd) and fix the path for flutter you should get the correct address for that for example: C:\flutter\bin
I can't run all of my flutter apps, because in the console appears everytime this error message:
Downloading Gradle Wrapper... 1,2s
Launching lib\main.dart on SM G960F in debug mode...
Running Gradle task 'assembleDebug'...
Finished with error: Unable to locate gradlew script. Please check that C:\Users\...\android\gradlew.bat exists or that C:\Users\...\android can be read.
I try to fix this problem more than ten hours and don't find a solution.
I will advise you to check your pc properly for unwanted programs. Something is preventing your pc from running the Gradle. I had the same issue only to realize that antivirus was installed on my pc alongside a cd burner that I just installed. Check for any antivirus that might be preventing Gradle from running.
I also faced the same error initially. While creating a flutter application from scratch I just ran the default flutter application which is a counter app in a flutter. I faced the same issue at first. If you are in this same context as described earlier the following could be the solution
1.Java 8 is more suitable for the flutter/android development. The next versions of java have some exceptions. I used the Java 14 and stuck at this issue for some time
The next could be the JAVA_HOME path in your environment variables. If it is not provided the set the JAVA_HOME path.
Run flutter --doctor and check the requirements if satisfied like Android SDK is updated or not, upgrade flutter if required. In some cases having good Internet connection also plays a role in this issue some times.
These are the major points to be satisfied in order to get rid of this error. Mostly this could be the a solution or part of it.
The error suggests that something is preventing gradle to run properly on your machine. Check whether you have any unwanted programs or anti-virus on your machine running that might be preventing gradle to run. If so, remove or stop those programs / anti-virus and try again.
After that, delete the .gradle folder located here C:\Users\yourPcName\.gradle containing the unfinished file and try again . It will work now .
You can also manually download Gradle and map it in Android studio , Learn more with this article here .
Warning, the gradle versions change quickly, so make sure you manually
downloaded the exact version that flutter wanted to download and the
download failed. Download the gradle here and then replace it in the
gradle folder.
C:\Users\yourPcName\.gradle\wrapper\dists\gradle-x.x.x-all
If it still doesn't work,
Try to run flutter --doctor
From a console window that has the Flutter directory in the path (see above), run the following command to see if there are any platform dependencies you need to complete the setup:
C:\src\flutter> : flutter doctor
This command checks your environment and displays a report of the status of your Flutter installation. Check the output carefully for other software you might need to install or further tasks to perform (shown in bold text).
You can learn more here :
If flutter doctor itself doesn't work, then know that flutter is not installed on your machine (or you forgot to add it to the environment
variable).
I also faced this problem and I made something to run my app on android
tried to open anything on android files and android studio ask me if I want to open for editing android file in android studio then click on it and it will open android project then click run enter image description here
