`flutter config --android-sdk /opt/android-sdk/` not working on arch linux how can i configure?

I am installing flutter without android-studio on arch linux with this guide: https://ksrk.medium.com/install-flutter-without-android-studio-on-ubuntu-a14a66a88f9f

and also this: https://dev.to/awais/configure-flutter-development-environment-on-manjaro-arch-linux-4a0a

$ flutter --version
Flutter 2.5.3 • channel stable • https://github.com/flutter/flutter.git
Framework • revision 18116933e7 (19 hours ago) • 2021-10-15 10:46:35 -0700
Engine • revision d3ea636dc5
Tools • Dart 2.14.4

I also installed Android SDK and configured PATH variables in my .zshrc file as you can see below.

# .zshrc

export JAVA_HOME='/usr/lib/jvm/java-8-openjdk'
export PATH=$JAVA_HOME/bin:$PATH 
export ANDROID_SDK_ROOT='/opt/android-sdk'
export PATH=$PATH:$ANDROID_SDK_ROOT/platform-tools/
export PATH=$PATH:$ANDROID_SDK_ROOT/tools/bin/
export PATH=$PATH:$ANDROID_SDK_ROOT/tools/
export CHROME_EXECUTABLE=/usr/bin/brave

Still, it gives me an error in flutter doctor so I have tried other commands also to configure it.

$ flutter config --android-sdk /opt/android-sdk/

still, it gives me an error in flutter doctor.

As you can also see it's detected Android SDK at /opt/android-sdk still it's giving me an error in Android toolchain.

I also can't set up a license without it.

$ flutter doctor --android-licenses
Android sdkmanager not found. Update to the latest Android SDK and ensure that the cmdline-tools are installed to
resolve this.

I have sdkmanager in my PATH variable and also working still gives an error

$ which sdkmanager
/opt/android-sdk/tools/bin/sdkmanager

I don't want to install android studio because I don't want to run it in an emulator I want to run on my mobile directly with hot reload so I don't have to install android on my os.
