Resolve First Problem: Android Command Line tool

Android devices (Android SDK version 35.0.0)
X cmdline-tools
component is missing
Run
`path/to/sdkmanager --install "cmdline-tools;latest"`
See

Solution
The solution for me was
opening Android Studio and going to SDK Manager, switch to the SDK Tools tab and check Android SDK Command-line Tools
(latest).
Don't forget to add to
your PATH the tools and platform-tools folder that are inside your SDK.
Eg: Open Edit Environment
PATH variables and add
1.
First Path is path for Flutter SDK
2.
Other two are for the platform
C:\Users\Gest\dev\flutter\flutter\bin
C:\Android\Sdk\platform-tools
C:\Android\Sdk\platforms
2. Accept
Licenses
After resolving above issue, Now
let’s run Flutter doctor again
You will see Next issue
Some Android licenses not accepted. To resolve this,
run: flutter doctor --android-licenses
C:\Project\MyProject\Waste\1\app_1>flutter doctor
