Material Design sticker sheet by Google
Google itself recently released this sticker sheets on its Material Design website.
This is a newer version of the Material UI kit already included in Adobe XD by default.
This sticker sheet includes the elements that make up layouts, including light and dark symbols for status bars, app bars, bottom toolbars, cards, dropdown menus, search field, dividers, side navs, dialogs, floating action buttons, and other components.
The sticker sheet elements align to an 8dp grid. Type baselines fall on a 4dp grid.
Most of the main objects like buttons and icons are already saved as Symbols, which is quite handy.
The Adobe XD version can be downloaded for free from the Material.io website.
