when using The props or button loading will get a error , and other is work.

[feaverfei]

Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: undifined. Check the render method of 'Button'.

<Button isLoading={true} style={styles.buttonStyle7} textStyle={styles.textStyle6} onPress={() => { console.log('world!') }}> Hello </Button>

it can"t work.

<Button style={styles.buttonStyle6} textStyle={styles.textStyle} onPress={() => { console.log('world!') }}> Hello </Button>

it can work

Hello @feaverfei!

I need more info to debug, RN version, platform, button version, etc.

Checking the example, the isLoading prop works perfectly.
