[dpilch]

• add react attr generation for collectionBindingProperties

Previously:

{(item, index) => (
  <Flex {...props} {...getOverrideProps(props.overrides, "Flex")}>
    <Button
      label
      labelWidth={width}
      backgroundColor={buttonColor.favoriteColor}
      disabled={isDisabled}
      {...props}
      {...getOverrideProps(props.overrides, "Button")}
    ></Button>
  </Flex>
)}

After change:

{(item, index) => (
  <Flex {...props} {...getOverrideProps(props.overrides, "Flex")}>
    <Button
      label={item.username || "hspain@gmail.com"}
      labelWidth={width}
      backgroundColor={buttonColor.favoriteColor}
      disabled={isDisabled}
      {...props}
      {...getOverrideProps(props.overrides, "Button")}
    ></Button>
  </Flex>
)}
