Flutter is a strong contender for cross-platform development, offering fast development and great design potential but with a few limitations. It's ideal for projects aiming to run on multiple platforms without significant performance trade-offs.
The best cross-platform development framework I have tried. Includes TWO great widget libraries to get you started off right, and performance that is blistering fast compared to other cross-platform solutions. I basically can't tell that the end products aren't UIKit or SwiftUI. Truly an awesome framework!
