Is there a way to adjust layouts in flutter after using user interfaces made with figma?

I recently started working with figma and I’m still quite new to everything. I made a lot of progress though and everything was going great until I realized I forgot to apply “auto layout” to every ui I made and applying it now would make me start adjusting everything from scratch. But since I’m turning all ui’s to flutter code, is there a better way to make layout adjustments after or do I have to start from the beginning?
