How to use custom local font in Vaadin 10 ?

I have a problem with using local fonts with vaadin flow. How can i use custom fonts in my project ? Any suggestion ?

There shouldn’t be any difference to a normal web project. Though, to apply the font family to all Lumo styled components, you need to set the CSS custom property:

html {
  --lumo-font-family: your-local-font-name, ...;
}

See https://cdn.vaadin.com/vaadin-lumo-styles/1.0.0-beta3/demo/typography.html for more info.
