Learning Flutter (Part 1 - Install Flutter)

 Trying to learn something new. Want to start with Flutter first. I do have some experience developing Android APP but that was a decade a ago. Using Android SDK to develop from scratch. However as time changed in a glimpse. Now its time to explore a new SDK!

Flutter~

 

First i followed the instructions on how to install Flutter on my linux machine

https://docs.flutter.dev/get-started/install/linux

encountered few issues. 

  1. [!] Android toolchain - develop for Android devices (Android SDK version 29.0.3)
        ✗ cmdline-tools component is missing
          Run `path/to/sdkmanager --install "cmdline-tools;latest"`
          See https://developer.android.com/studio/command-line for more details.
        ✗ Android license status unknown.
          Run `flutter doctor --android-licenses` to accept the SDK licenses.
          See https://flutter.dev/docs/get-started/install/linux#android-setup for more details.
  2. [✗] Chrome - develop for the web (Cannot find Chrome executable at google-chrome)
     

Ok lets fix the first one first!

     ✗ cmdline-tools component is missing

This issue might due to the missing Android SDK from my machine. or miss PATH set. ok..

 I checked if i did installed Android Studio before? 

/opt/android-studio/bin/studio.sh

YUP. I did! made a simple web launcher app for FOODAH on 2020 aha! long time didnt touch Android Studio. Reason why i dont remember where is the SDK path, by opening the Android Studio i able to see the path set.

ok now setting the android path 

vim ~/.bashrc 

added the lines below~

export ANDROID_HOME=/home/alia/Android/Sdk
export PATH=$PATH:$ANDROID_HOME/tools
export PATH=$PATH:$ANDROID_HOME/platform-tools

reload the bash profile

source ~/.bashrc

check the path

echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/home/alia/Android/Sdk/tools:/home/alia/Android/Sdk/platform-tools

ok after checking the path. i still could'nt locate the SDKManager tool. Probably my installation was way back too outdated.

 https://developer.android.com/studio/command-line/sdkmanager

you can find the commandline tools available for download at the bottom page 

https://developer.android.com/studio



 ok downloaded. and i stored the commandline tools at my sdk path.

java path and commandline-tools path is correct yaaaa

~/Android/Sdk/cmdline-tools/latest/

 

    ✗ cmdline-tools component is missing
      Run `path/to/sdkmanager --install "cmdline-tools;latest"`
      See https://developer.android.com/studio/command-line for more details.

By right the first issue should solved by now! 


moving to the next issue.


       Run `flutter doctor --android-licenses` to accept the SDK licenses.

settled. just accept the terms and condition.


next issue 

[✗] Chrome - develop for the web (Cannot find Chrome executable at google-chrome)

set the google chrome path. to find the chrome bin path, can run this in the browser address bar 'chrome://version'

export CHROME_EXECUTABLE=/snap/chromium/1944/usr/lib/chromium-browser/chrome
 

finally run back the flutter doctor command yezzaa everything is ready!

 

alia@alia-K45VD:~/coding$ flutter doctor
Doctor summary (to see all details, run flutter doctor -v):
[✓] Flutter (Channel stable, 2.10.3, on Ubuntu 20.04.2 LTS 5.4.0-99-generic,
