Navigation.navigate is not a function, navigation is undefined

I have a problem, in React-Native.

<Button title="Save" onPress = {() => navigation.navigate('Save' , { image })}/>    {image && <Image source = {{uri: image}} style= {{flex: 1}}/>}</View>  );}

I got an error:

navigation.navigate is not a function. (In 'navigation.navigate('Save', {image: image})', 'navigation.navigate' is undefined)
