flutter is not running on windows

flutter is not running on windows - flutter

After installing flutter and running my emulator it stops at initializing gradle on android studio and on vs code.
It outputs:
this is taking an unexpectedly long time.
I ran flutter doctor and no issues and also flutter doctor -v and still no issues. I tried flutter upgrade but still no difference.
What is the next thing to try?
flutter error log

It looks like it is just taking forever to start; You can read the thread on the issue on
Github:
To summaries: here is one of the issues: Downloading 400mb of dependencies
Solved Initializing gradle problem
The problem is that when first time we are trying to run our flutter
project it does not have the required flutter gradle file. The
required file size that gradle downloads is about 300-400MB that's why
it takes so much time. Following are the steps:
Run your project by clicking on the 'Run' button or flutter run in the command terminal
Then go to the place where your .gradle file is located (usually it is in the C:\Users). In the .gradle folder there is file
name as wrapper in this there is dists folder. In dists folder there
is gradle folder which is being downloaded.
wait till the gradle file is being downloaded and after sometime your project would compile.
its working thaaaaaanks
I am new to mobile development; Everything takes eternity.

Solved this issue by removing all the gradle files from
C:\Users\.gradle\wrapper\dists
Now when you run your flutter app, it will automatically download the required gradle files.
Enjoy!!!

This will remove you build file and re-create it.
Your problem should have solved now.

Gradle (Flutter) does not use the cache

I'm giving Flutter a try, I'm totally new.
I added gradle in:
[project_directory]/android/gradle/wrapper/gradle-wrapper.properties:
distributionUrl=file:///run/media/me/gradle-7.2-all.zip
The first time I ran the flutter run command all dependencies were downloaded. But now when I create a new project, it downloads them again from the internet and doesn't use the previous cache. In fact, if I change something in pubspec.yaml, like adding assets, when I run flutter run it tries to download the internet dependencies again.
Am I missing any settings here?
Flutter 3.1.0 | Dart 2.18.0 | Gradle 7.2 | Linux

for .yaml run 'flutter pub get' command in terminal

I recently Solved this problem.
This Problem came from gradle file is corrupted in my system.
I'm using Linux so this steps almost same in windows also. This answer is for any gradle version.
Open File Manager:
enable Show hidden folder from top menu bar.
You may find this location : .gradle>wrapper>dists.
In Linux: Home > .gradle > wrapper > dists.
In Windows: C:>Users>{PC Name}>.gradle>wrapper>dists
Method 1
Go inside gradle-6.5-all > dists > 2oz4ud9k3tuxjg84bbf55q0tn. '2oz4ud9k3tuxjg84bbf55q0tn' may be different in your PC.
Delete all files in that folder and download required file manually: https://downloads.gradle-dn.com/distributions/gradle-6.5-all.zip
after download paste freshly downloaded zip file in that folder.
Run your project flutter run -v
Method 2
Try this if you have fast & stable internet connection.
Delete that gradle-6.5-all folder.
Open project in VS code or Android Studio and open terminal.
Run this command flutter run -v
Method 3
Flutter Doctor will give right result.
Open Android Studio
Create new flutter project
Click on Tools > flutter >Flutter for editing in android studio
and wait, flutter doctor takes time to identify problem.
Use this link for download gradle file.
Replace 6.5 with your gradle version.
https://downloads.gradle-dn.com/distributions/gradle-6.5-all.zip
I hope this answer helpful for you.

Please use the below command
1.Mac User :
rm -rf ~/.gradle
2.Windows User :
remove the .gradle file
.gradle file location -> C:\Users\myUser

I solve this error by updating the gradle plugin/version. I have as part of my configuration:
Windows 10
Android Studio 4.2.1
Java 11: Android Studio 4.2.1 don't have support for JDK 16, so, I installed JDK 11, and configured the AS (how to change the jdk in AS) to use this older JDK
Gradle 7.0.1
By default, when you create a new Flutter project, the IDE created it with basic standard configurations, so you have to change this configs to fit your current config. For that, you need to update the gradle config in the flutter project, as follow:
in android/gradle/build.gradle file: update the gradle plugin to 4.2.0 in the dependencies section, like this:
dependencies {
classpath 'com.android.tools.build:gradle:4.2.0'
//more dependencies
}
in android/gradle/wrapper/gradle-wrapper.properties file: update the gradle version, in this case I have the 7.0.1, feel free to use another one, like this
distributionUrl=https\://services.gradle.org/distributions/gradle-7.0.1-all.zip
//more attributes
After you change the gradle config, run this commands in your project:
flutter clean : clean the project
flutter pub get : update your dependencies
flutter run : run the project. Now it must work, at least it work for me

I faced the same problem in VSCode when I wanted to run the Flutter app I got that error, so after lots of debugging and research, I found the solution. it's pretty easy, just follow these steps:
In windows 10:
1. Open flutter project in a Text-Editor like VSCode.
2. Open android -> gradle -> wrapper -> gradle-wrapper.properties
3. You will find "gradle-6.7.1.all.zip" inside gradle-wrapper folder
4. Go to this path: C:\Users\your-user
5. Then go to the wrapper->dists and find "gradle-6.7.1.all" folder
5. Delete this folder.
6. Then come to VSCode and open Terminal.
7. Please make sure that you have stable internet connection then type this command in terminal
8. flutter run
I hope this solution can help you!

I solve this error by deleting the .gradle folder.
This location is gradle folder
In Windows: C:> Users> {PC Name}>. Gradle
After deleting this folder, you only need to run the application again in Android Studio. At this point, Android Studio starts downloading the deleted folder automatically.
enter image description here

This error is caused by corrupted gradle files, this is either due to incomplete downloads due to network issues. To solve it easily download the gradle zipped file from https://downloads.gradle-dn.com/distributions/gradle-6.7-all.zip and paste on the .gradle directory as shown below if you are on linux
enter image description here

I try all method but it did not work for me so i decided to location the gradle-wrapper.properties in the andriod folder then i change the distribution gradle link to a more recent gradle link.

Welcome SO.
Java 16/latest version is not fully compatible with the Gradle 6 at this moment. Try to use java 11 or 8, it will resolve your issue.

Flutter App stuck at “Running Gradle task 'assembleDebug'… ”

Please I need Help Solving this Issue
I have been running my flutter app without issues, but recently I can't run or debug my apps again, each time I try running my app from the terminal or debug console it always get stuck at Flutter App stuck at “Running Gradle task 'assembleDebug'”
C:\Development\projects\flutter>cd kchat
C:\Development\projects\flutter\Kchat>flutter run
Running "flutter pub get" in Kchat... 3.6s
Launching lib\main.dart on GIONEE S10C in debug mode...
Running Gradle task 'assembleDebug'...
(This is taking an unexpectedly long time.)

I have solved the problem by running
flutter run -v
it fixed all the problem but took a longer time, and I can now use
flutter run
but still can't use Debug console

Alternatively, try to fix your project.
Delete the android folder in your project, having previously saved it in another place, then in the terminal run flutter create your_project_name for the folder in which your project is located.

Task :app:compileFlutterBuildDebug FAILED (Flutter)

I have issue to run demo flutter project.
log verbose :

you can try to use command
flutter clean
and then flutter run

The error might be due to the improper installation of SDK. There are several solutions as per below:
1) Invalid Cache and restart. (the common one)
2) Reinstall flutter SDK.
3) Change the gradle version with the available version of your machine.
4) Removing "android.enableR8=true" line from the android project's gradle.properties file.
