Can you, please, give any context? The error is quite clear. If it happens during calling vibrate without arguments - it's a bug, yeah. Otherwise, you'll have to fix it yourself.

According to the error, you have 4 timings and 2 amplitude values. Those arrays should be equal.

@benjamindean This line from the document cause error: Vibration.vibrate(pattern: [500, 1000, 500, 2000], intensities: [1, 255]); Obviously the amplitude was not provided, only the intensities.

any solution of this issue.
