title: How do I mix multiple gradients in Flutter?
body: <p>The designer has combined two or more gradients in the Figma Design they created. In some designs, they have combined a radial gradient with a linear gradient; while some other designs, they have combined a linear gradient with another linear gradient.</p>
  <p>This is something that can easily be done with CSS, but, in Flutter, I haven't been able to implement it. I have read almost all documentation of Flutter but no solution seems to be in sight. Is there anyway I can combine two gradients without having the designer change the design?</p>
