Responsive UI Implement for flutter mobile and web apps. I am very familiar with responsive flutter UI. Set the width and height of the design draft, and clone widgets's size, padding, margin, spacing and font size according to the design.(Zeplin, Figma, Adobe XD and so on). Then, all of the components of the design have the same ratio on different screen sizes. I am using a well-structured project template using this package and all of UIs will build almost one codebase for mobile, tablet, desktop, TV design.
