  onChangeText={text => this.updateContent(text)}
  
  
  
  updateContent(newText) {
    this.setState({ contentText: newText });
    firebase.database().ref('kettles/' + this.state.currentKettle + '/').set({
      content: newText
    });
  }

One note, I would move the function in:

onChangeText={text => {
    this.setState({ contentText: text });
    firebase.database().ref('kettles/' + this.state.currentKettle + '/').set({
      content: text
    });
}}```
