Configuring the defaultNavigationOptions
as such:
defaultNavigationOptions: {
headerStyle: {},
headerBackImage: <Image source={require('../assets/icons/back.png')}/>,
headerBackTitle: null,
headerLeftContainerStyle: {},
headerRightContainerStyle: {},
}
within the createAppContainer method immediately throws
TypeError: undefined is not an object (evaluating '_react.React.createElement')
The image is definitely at the correct location, and commenting out the headerBackImage
property resolves the problem. Is this bugged?
please check if you're correctly importing React as the default import
check the links below where other developers had the same issue as you and solved their problems by correcting this
TypeError: undefined is not an object 'createElement' of undefined - React Native
TypeError : React object is undefined on createElement
let me know if this solves your problem
