"Gradle task assembleDebug failed with exit code 1" because "Could not find or load main class org.gradle.wrapper.GradleWrapperMain"

I'm new to flutter and I want to make the default flutter app to show up on my Android emulator. The emulator starts up fine but the process fails at "gradle task assembleDebug". I reinstalled everything ranging from Android Studio to flutter and dart and also deleting the AVD from Android Studio then creating it again but nothing seems to work. I tried a few potential fixes from youtube and google searches involving running a "gradle wrapper" command at the root directory but that doesn't work too as the root directories of all flutter apps lacks the "build.gradle" file. Flutter doctor does not show any problems.
"flutter doctor" command output:
PS C:\Users\Mahmud Alam\Desktop\Programming Stuff\Flutter&Dart\newproj\firstapp> flutter doctor

I get the feeling that something is missing from somewhere but I cant figure out where and how to restore the files that are missing. Also, I'm running an emulation of Pixel 2 API 30 (android x86). But that alone should not cause any problems. How do I fix this?

I think this is your "&" of Flutter&Dart which cause the problem.

Try running flutter clean in your terminal and then rebuilding the app, that's worked for me in the past.

Delete the flutter cache (/bin/cache);
Delete gradlew and gradlew.bat in android folder (and in some cases android/gradle/wrapper/gradle-wrapper.jar too);
Run flutter run again.
This steps worked for me.

Exception: Unable to generate build files in flutter

I am trying to install flutter in kali linux machine. I installed flutter from official website and followed accordingly. I don't want to use android studio so I am using visual studio code.
when I run Flutter doctor in terminal i get
[✓] Flutter (Channel master, 2.2.0-11.0.pre.161, on Linux, locale en_IN)

And when i Run in visual studio i get this

lib/main.dart:1
CMake Error: CMake was unable to find a build program corresponding to "Ninja". CMAKE_MAKE_PROGRAM is not set. You probably need to select a different build tool.
CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage
Exception: Unable to generate build files
Exited (sigterm)
Can anyone help me with this issue please.

I found the solution by using this following command:
sudo apt-get install clang cmake ninja-build pkg-config libgtk-3-dev
and
flutter config --enable-linux-desktop

you must install ninja.
sudo pacman -S ninja or sudo apt-get install ninja.

i have see many issues like this with answers here but non fixed my issue... i have tried deleting "gradle-wrapper.jar" and Replacing "distributionUrl=https://services.gradle.org/distributions/gradle-x.x.x-all.zip to gradle-6.4.1-all.zip" on the gradle-wrapper-properties file and running the comman "flutter run" on my terminal but still get same error
i have tried "flutter doctor" which gave me the result down bellow

i know i have not installed Xcode which i will do later but am not sure if thats the issue
#what am i doing wrong?

Looking at the path, the error clearly stated that:
Caused by: java.net.URISyntaxException: Illegal character in path at index 62: https://services.gradle.org/distributions/gradle-x.x.x-all.zip to gradle-6.7-all.zip
When checking the file gradle-x.x.x-all.zip in services.gradle.org/ distributions/, it is not existing while the gradle-6.7-all.zip was found. So it could be a big factor that there was an error copying the distributions path. The proper file should be gradle-6.7-all.zip.
Also, you've mentioned that this was the first time Flutter was setup in your MacOS. With this, you can always check the guide from the Flutter documentation about macOS install for any missed steps/processes.

The error shows your characters in "distributionUrl=https://services.gradle.org/distributions/gradle-xxx-all.zip to gradle-6.4.1-all.zip"
Just change it to something like this:

Reinstalled all SDK packages several times, i have attached image of all SDK packages for refernece.Please have a look.

Tried using earlier version of flutter and tried again after upgrading it.
After doing all this I am still getting this error for all projects. Even the basic project which is pre-written when creating a new flutter project.

When I run flutter. Xocde build done then give the Error ProceesTimw out. Then I try every thing that i can try. I install new vwesion of Xcode 11.4.1 and flutter new version 1.17 stable enter image description here

For me, I had the same issue and resolved it by moving my project out of a folder that iCloud was backing up. I had moved to a place with slower wifi, so my project kept hanging. Now, it loads faster than it did before.

This usually happens when you update xcode to fix this use Flutter upgrade in your general terminal and go to your project code editor and run Flutter clean and run flutter run if you face any other issues let me know......
