React native not finding sdk, even using local.properties with correct path

I already created local.properties in the android folder

sdk.dir = home/user/Android/Sdk

And already added those lines in .bashrc and also ~/.zshrc:

export ANDROID_HOME=$HOME/Android/Sdkexport PATH=$PATH:$ANDROID_HOME/emulatorexport PATH=$PATH:$ANDROID_HOME/toolsexport PATH=$PATH:$ANDROID_HOME/tools/binexport PATH=$PATH:$ANDROID_HOME/platform-tools

I did test those variables using echo, it is all there. So why RN can't find the sdk?

PS: i'm using Ubuntu 20.
