how to use intensifies about flutter_vibration HOT 4 CLOSED

@benjamindean yep, i just missed the thing that you have to either use duration and amplitude, or pattern and intensifies

all works fine for me now

but, i now i think you should either add assertions for that, or make another method and move the pattern vibration in there. current api is a little bit confusing imo

from flutter_vibration.

You have to provide the pattern for that. In you example, it'll vibrate only once.

@benjamindean so what's the correct code for the behavior i want to achieve?

i still don't understand
does intensifies automatically interpolate the vibration values and this code will be correct?

Vibration.vibrate(
  duration: duration,
  pattern: [0, duration],
  intensities: reverse ? const [255, 1] : const [1, 255],
);

or i have to specify all of them

final intensities = List.generate(255, (i) => i + 1);
Vibration.vibrate(
  duration: duration,
  // generates a pattern [0, 0.4, 0, 0.4, 0, 0.4, 0, 0.4, 0, 0.4, .......... ]
  pattern: List.generate(255 * 2, (i) => i).map((el) => el % 2 == 0 ? 0 : duration / 255).toList(),
  intensities: reverse ? intensities.reversed.toList() : intensities,
);

which is correct?

upd: it's not really easy to test on real device for me so i'm asking you to explain how this intended to work, and please, explicitly document this, it's not obvious at all

@nt4f04uNd Have you checked the examples in README? You should specify either duration or pattern in milliseconds with intensities list.
