Changing the space bettwen the indicators

You can change the padding around the indicators using the indicatorPadding property:

return PageViewIndicator(
  pageIndexNotifier: pageIndexNotifier,
  length: length,
  indicatorPadding: const EdgeInsets.all(4.0)
  ...

Default is const EdgeInsets.all(8.0).
