Flutter Fastlane Gitlab Build

I am new to Fastlane and want to build my apk through the Fastlane and Gitlab. I have been getting this error whenever I run the Fastlane command:
FAILURE: Build failed with an exception.
* Where:
Build file '/builds/sw/pro/pro_app_flutter/android/app/build.gradle' line: 30
* What went wrong:
A problem occurred evaluating project ':app'.
> Could not read script '/Users/your-user/Library/Android/flutter/packages/flutter_tools/gradle/flutter.gradle' as it does not exist.
But I am unable to figure this out, what does this mean because flutter.gradle does exist on the path!
Moreover the build from Android Studio is successfully generated!
Thanks in advance
P.S my fast file:
default_platform(:android)
platform :android do
desc "Build a Flutter apk1"
lane :buildDebug do
gradle(task: "assemble", project_dir: 'android/')
end
end

React-native-blob-util couldn't find ANDROID_SDK_ROOT

npx react-native run-android causes the following error with module react-native-blob-util on Big Sur/React Native 0.66.1/Android Studio 2020.3.1:
FAILURE: Build failed with an exception.
* Where:
Build file '/Users/macair/Documents/code/js/xyz_app5/node_modules/react-native-blob-util/android/build.gradle' line: 69
* What went wrong:
A problem occurred configuring project ':react-native-blob-util'.
> SDK location not found. Define location with an ANDROID_SDK_ROOT environment variable or by setting the sdk.dir path in your project's local properties file at '/Users/macair/Documents/code/js/xyz_app5/android/local.properties'.
The line of code in react-native-blob-util 0.13.16 build.gradle which causes error is:
classpath += project.files(android.getBootClasspath().join(File.pathSeparator))
But a .bash_profile has been created with ANDROID_SDK_ROOT defined. Also in project structure under android studio SDK has been defined and pointing to /Library/android/sdk. What is really missing here?
Here is the SDK defined in project structure:

After installing Android 10 by following setup for Android in React Native, the error disappeared.

Been trying to debug this issue for hours! Tried many solutions online, none seems to be working.

How do I fix this?

Finally got it fixed! Not sure which one of the following fixed it though.
Change $ANDROID_HOME inside ~/.bashrc from ANDROID_HOME=$HOME/Android/Sdk to ANDROID_HOME=$HOME/Android/Sdk/platform-tools
Deleted version 25's folder inside platform-tools folder in the Sdk and installed version 25 again.
After doing the two above, restarted the system and I am now able to compile and build ionic app to .apk files.
PS : This might be just only in my personal computer, and you might be facing the same issue due to different issue. Hope this helps.

Make sure you have an Android emulator running or a device connected and have
set up your Android development environment:

As you can see from the error you need to move your project to a different directory with no non-ASCII characters.

Android Studio multi-dex gradle doesn't recognize java on mac

I'm trying to compile a gradle project (plugin 0.14.0) with multi-dex on my Mac, and getting this error:
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':ApplicationContainer:createDebugMainDexClassList'.
> java.io.IOException: Cannot run program "java": error=2, No such file or directory
Any suggestions?
When I execute ./gradlew from terminal, it works.

Found a solution.
Seems like Android Studio didn't inherit environment path or something.
I ran it from the terminal:
open /Applications/Android\ Studio.app
And it solved it.
More elegant solutions will be happily accepted :D
