Problem with android SDK and Flutter plugins

I tried many ways but i cant fix these problems. :( Im new to flutter.

[X] Android toolchain - develop for Android devices X Unable to locate Android SDK. Install Android Studio from: https://developer.android.com/studio/index.html On first launch it will assist you in installing the Android SDK components. (or visit https://flutter.dev/setup/#android-setup for detailed instructions). If the Android SDK has been installed to a custom location, set ANDROID_HOME to that location. You may also want to add it to your PATH environment variable.

[√] Android Studio (version 3.4) [!] Android Studio X Flutter plugin not installed; this adds Flutter specific functionality. X Dart plugin not installed; this adds Dart specific functionality. X android-studio-dir = /path/to/android/studio X Android Studio not found at /path/to/android/studio [√] VS Code, 64-bit edition (version 1.31.1) [!] Connected device ! No devices available
