Flutter -v
Manage your Flutter app development.
Common commands:
flutter create <output directory>
Create a new Flutter project in the specified directory.
flutter run [options]
Run your Flutter application on an attached device or in an emulator.
Usage: flutter <command> [arguments]
Global options:
-h, --help Print this usage information.
-v, --verbose Noisy logging, including all shell commands executed.
If used with "--help", shows hidden options. If used with "flutter doctor", shows additional diagnostic information. (Use "-vv" to force
verbose logging in those cases.)
--prefixed-errors Causes lines sent to stderr to be prefixed with "ERROR:".
--quiet Reduce the amount of output from some commands.
--[no-]wrap Toggles output word wrapping, regardless of whether or not the output is a terminal.
(defaults to on)
--wrap-column Sets the output wrap column. If not set, uses the width of the terminal. No wrapping occurs if not writing to a terminal. Use "--no-wrap" to
turn off wrapping when connected to a terminal.
-d, --device-id Target device id or name (prefixes allowed).
--version Reports the version of this tool.
--machine When used with the "--version" flag, outputs the information using JSON.
--[no-]color Whether to use terminal colors (requires support for ANSI escape sequences).

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

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:

--proxy_port=<port #>: Proxy port to connect to.
* If the env var REPO_OS_OVERRIDE is set to "windows",
"macosx", or "linux", packages will be downloaded for that OS.
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

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......
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.
