Web Renderer

There are two renderer, HTML renderer and CanvasKit renderer. Also you can specify the renderer in Settings, the change will take affect at next loading or page refreshing.

By default, canvaskit renderer is used.

HTML Renderer

Uses a combination of HTML elements, CSS, Canvas elements, and SVG elements. .

  • advantages: This renderer has a smaller download size, can use system fonts
  • disadvantages: page layout may be broken, like incorrect font size calculation.

CanvasKit Renderer

  • advantages: fully consistent with Flutter mobile and desktop, has faster performance with higher widget density it's laggy and annoying.
  • disadvantages: larger app size, especially the first loading. Need to download then render Google fonts at runtime. It may take several seconds before you can see the correct characters.


Automatically choose renderer by flutter.
