Open callmejm opened 7 years ago

I getting this error when try to use BoxShadow in my project.

Warning: Each child in an array or iterator should have a unique "key" prop.
Check the render method of `BorderShadow`. See https://fb.me/react-warning-keys for more information.

you must set up a key param when you are using a loop that output ReactElements, for example

items.map((item,i) => <View key={i}>{i}</View>)
