On MacOSX, when I run flutter doctor, the following result is shown in the terminal:

The line following error is strange.
[!] Android toolchain - develop for Android devices (Android SDK
version 29.0.3)
✗ Android SDK file not found: adb.
Android SDK is installed
Platform tools are installed
If I run adb devices on my terminal, everything works fine and my device appears.
Any idea on how to fix this?
So I fixed in a very strange way:
Seems like some new version of Android SDK moved adb from /sdk/platform-tools to /sdk/platform-tools/platform-tools
To fix, I've only moved adb from /sdk/platform-tools/platform-tools to /sdk/platform-tools and now it's working.
Starting with the less complex fix;
Open vscode, click on the extension tab then search and install flutter extension.
Open the App Store search and install Xcode. It takes a very long time to complete. Clearly your installation is not complete.
If you are sure you have android SDK downloaded, then use the following command to provide the path the android studio. flutter config --android-sdk <path-to-your-android-sdk-path>
. Else you can use android studio to download the required Android SDK. See location in picture
Installing Xcode in the App store will install cocaopods. Then try flutter doctor -v and everything will be good.
NOTE: you don't need adb in mac for flutter to compile on android. downloading an Android SDK will install qemu. You will also notice some significate process load while running an Android emulator because of the running qemu process since it is not very optimized fro mac. But that is not an issue you will get use to or just use a real android device. Install Xcode will install all Iphones simulators.

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

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.

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:

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......
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.
