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
Launching lib/main.dart on Linux in debug mode...
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.

Byw I m using VS Code but on termux and I m new to flutter and this is my first app.

Set ANDROID_SDK_ROOT variable under system variables.
You also need to restart the android studio after setting system variable.
For ex.
ANDROID_SDK_ROOT = "C:\Android\SDK"

This is for Ubuntu. Change the path to your SDK directory.
export ANDROID_SDK_ROOT=/usr/lib/android-sdk
This is for windows. Change the path to your SDK directory.
set ANDROID_SDK_ROOT="C:\installation location\android-sdk"

This is for windows. Change the path to your SDK directory.
on windows
set ANDROID_SDK_ROOT="C:\installation location\android-sdk"
on linux
export ANDROID_SDK_ROOT=/usr/lib/android-sdk

So how can I activate the license for android SDK?

I had the same issue when I ran flutter doctor --android-licenses. And I had android SDK installed without using Android Studio.
Here are the steps I took to make it work
I went to android studio download page and scrolled down and downloaded the command line tools for my OS (windows)
Then I extracted it to the android-sdk directory
I created a new folder called latest inside cmdline-tools and moved the content of cmdline-tools to it.
After this I tried to run flutter doctor --android-licenses and then it worked without errors and ran it on my device no problem.

Install Android SDK 6.0(Marshmallow)

I solved it by installing android studio and uninstall all android files and reinstall from android studio. Then automatically the license created in the folder. now whenever I run the emulator from vscode.. it is working smoothly.
I faced the problem because I installed all android files from android sdk directly. I installed android sdk by sudo snap android-sdk. so it created the problem for me.
To know more in detailed you can read this article - Flutter, Android SDK and VScode setup on Linux Complete Guideline

This issue would occur if you do not have the command-line tools in your <sdk>/cmdline-tools\latest directory. Instead of installing Android Studio, you can download command line tools from here and put it in the directory <sdk>/cmdline-tools\latest

Dart in Android Studio. No device to run applicaton

I can't run application because there is no devices on the list.
I tried to create AVD and connect real device. I have installed curl, Android SDK path was set, flutter licenses were accepted. I have Ubuntu 16.04.4
Output of flutter run --verbose in projects directory :
flutter: command not found
I have flutter path:
$ export PATH=/home/joe/flutter/bin:$PATH
$ echo $PATH
/home/joe/flutter/bin:home/joe/flutter/bin:home/joe/flutter/bin:/home/joe/bin:/home/joe/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin
Now I put path's to .bashrc and run source ~/.bashrc, did I put path's correct way ?
# set PATH so it includes user's private bin directories
export PATH=/home/joe/flutter/bin:$PATH
export ANDROID_HOME=$HOME/Android/SDK
export PATH=$PATH:$ANDROID_HOME/tools
After adding path's to .bashrc I run flutter doctor:
$ /home/joe/flutter/bin/flutter doctor

Can be easily fixed by setting project SDK to latest Android API.
Go to File
Project Structure
Under Project-SDK select the latest SDK installed(Example:- Android API 29 Platform).

You have to set an Environment variable.

Here is how i solved this problem:
First, I renamed AndroidSDK\tools to AndroidSDK\tool.
Then, I set the windows' environment variable Path from AndroidSDK\tools to AndroidSDK\tool (maybe not necessary)
Run sdkmanager --update in tool\bin .
Ignore the warning and wait until the update is done.
There will be a new folder named tools in AndroidSDK.
Copy all the files in tools folder and paste them to tool folder.
Overlay all the files that which has the same name in tool folder.
Finally,delete tools folder and rename tool to tools.
Problem solved.
