if you're using Windows, Go to the root directory C:\Users\YourUser and locate the hidden .gradle folder and delete it.
and then run your app connected to an Android emulator or device, don't cancel and make have a stable internet connection, this will download fresh Gradle
If the problem persists, Can you please provide your flutter doctor -v and flutter run --verbose logs, and a minimal complete reproducible code sample

I am a student.
I am trying to run this app created by flutter but I get this error. I disabled all Java options yesterday thinking that was the problem
I am running on flutter version 2.10.3, dart version 2.16.1.
Try upgrading gradle version and the run "flutter clean" command in terminal and then try to build the project.
I'm learning flutter for the first time using vscode and I'm getting this error where my app won't run. It happens when the app tries to run the Gradle task 'assembleDebug'. I don't know what Gradle is however, so I don't have a clue what's going on, any help on how to resolve this error would be greatly appreciated. This is the full error message:

I found a solution. The issue was with Gradle interacting with my installed Android Sdk, so using the Sdk manager in Android Studio, I uninstalled the current Sdk platform tools and then reinstalled them. This fixed the issue for me.

Can You help me Fight this issue?
I am Getting Gradle task assembleDebug error, also When I Run Flutter on Physical Device it Takes so much time to run and execute.
I want to seek help in this.
This could be caused by broken gradle installation or slow internet.
Solution:
Delete the .gradle folder located at Windows: C:\Users\<user>\.gradle or Mac: /home/<user>/.gradle
and then run the flutter app again.
It might take a little longer because gradle dependencies will be downloaded again. Don't disconnect your device.
This is my first flutter project and I am trying to just run the example one that comes with it. I did flutter run in the correct directory and I started an emulator. I am not sure what to do to fix it. At first, there was a problem where it would get stuck at Running Gradle task 'assembleDebug' then I allowed studio.exe and studio64.exe to be allowed through the windows defender firewall.
Here is the error.

Few days ago I had a similar problem like this.
https://github.com/flutter/flutter/issues/48159#issuecomment-571513079
Answer is from here, it solved my problem
C:\Users\uejaz.gradle\wrapper\dists\gradle-5.6.2-all\9st6wgf78h16so49nn74lgtbb
Move to this directory and delete gradle-5.6.2-all.zip and
gradle-5.6.2 folder
Goto
https://downloads.gradle-dn.com/distributions/gradle-5.6.2-all.zip and
download the zip file Replace the .zip file with the one you had
deleted earlier and extract the folder "gradle-5.6.2" in the same
directory. I hope it will solve all your gradle-related problems.
Note: if your gradle version is different than mine, just change the
version in the link provided above to download your gradle version.
Ops! you said I am trying to just run the example one that comes with it:
Those apps are implemented while ago. Please first try flutter upgrade and flutter clean.
If thats not worked check if distributionUrl is http. If so change it to https. Then do gradle build.
Your gradle-wrapper.properties file should be in flutter root project android directory. In my case it is C:\flutter_app\android\gradle\wrapper.
If this does not solved may be your gradle version in file system is broken. Deleting cache directory (C:\Users\usernmae\.gradle\caches) in .gradle and gradle build or sync from Android Studio will do the trick.

its because you dont have gradle-4.10.2 version on your computer.
Solution 1 using Visual Studio Code:
1. go to folder menu android->gradle->graddle-wrapper.properties
2. change gradle version to your computer version
Example: i have gradle version 5.4.1 on my laptop
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/**gradle-5.4.1**-all.zip
