Generate random numbers within a specific range

How do i generate 15 or more random number with range difference of 8-15

Eg If one of the generated number is 9 the next number should be either 17, 18, to 24 So the next number should not be less than 8 or greater than 15 Something like this

[5, 15, 23, 36, 45, 60, ......,]

Also it should start from 5 to 10

Please is this possible to achieve using javascript or flutter Also if you need more explanation or you don't understand please ask
