export PATH="$PATH:/op/flutter/bin:$JAVA_HOME/bin"
export ANDROID_HOME=/opt/Android/Sdk
export ANDROID_SDK_ROOT=/opt/Android/Sdk
export PATH=$PATH:$ANDROID_HOME/emulator
export PATH=$PATH:$ANDROID_HOME/tools
export PATH=$PATH:$ANDROID_HOME/tools/bin
export PATH=$PATH:$ANDROID_HOME/platform-tools
export PATH=$PATH:$ANDROID_HOME/tools
export PATH=$PATH:$ANDROID_HOME/tools/bin

Check that the java version is fine

java --version
sudo update-alternatives --config java
flutter config --jdk-dir=$JAVA_HOME
