The rate to hire one of our top Flutter Developers on an augmented staffing basis varies on seniority level. Our hourly rates range from $30 to $100 per hour. So for example, $30 per hour is for a developer that is at the junior level, whereas, $100 per hour would get you a developer who has high seniority. This would be a developer that could not only code your project but also serve as a Tech Leader for you.
