I use Huge Icons every day in my UI designs, it had thousands of icons across different styles. It is a must have library for designers. Implementation of the icons is very easy with SVG and Figma file provided by the designer. With figma file, it is easily integrated with Figma. I've never contacted for customer support as it is a easy to implement and use. Review collected by and hosted on G2.com.

I don't like that the Icons in the rounded categories are more than that of the Sharp section. And the flutter package has very limited icons, I hope the flutter package is from the same designer. Review collected by and hosted on G2.com.
