How to remove listener from Firebase Realtime Database

Question

For receiving data from Firebase Realtime Database I need to register listener:

objectReference.addValueEventListener(valueEventListener);

Answer 1

You can also do it like this:

  componentWillUnmount() {
    firebase.database().ref('example').child(this.state.somethingDyamic).off('value');
  };

  doSomething() {
    firebase.database().ref('example').child(this.state.somethingDyamic).on('value', (snapshot) => {
      ...
   });
  }
