Widget.Material
This module implements a Material design theme for all widgets.
The stylings are following the official Material Design guidelines as close as possible. Please use these widgets in combination with the official guidelines.
The typography is taken from the Material Design guidelines. Its recommended to use a font size of 16px width and the Roboto Font.
The style are not opaque, so you can change every styling to your needs.
If you have any suggestions or improvements, be sure to leave a PR or a Issue over at the github repos.

Button
Different styles for buttons have different meanings.
- Use
textButtonas your default button - Use
containedButtonfor any important action - Use
outlinedButtonif you have more then one important action. UsecontainedButtonfor the most important action of the group.
A contained button representing the most important action of a group.
A outlined button representing an important action within a group.
A text button representing a simple action within a group.
An single selectable icon.
Technical Remark:
- Could not find any specification details
A ToggleButton. Only use as a group in combination with buttonRow.
Toggle buttons should only be used with the iconButton widget, else use chips instead.
Technical Remark:
- Border color was not defined in the specification
- There are two different versions, one where the selected color is gray and another where the color is primary. I noticed the gray version was used more often, so i went with that one.
a Row of buttons.
Only use in combination with toggleButton
Switch
A boolean switch
Technical Remark:
- The specification states that the disabled switch should have a color dependent on its activeness. This is not implemented.
Card
A List styled like a card.
Technical Remark:
This is a simplification of the Material Design Card and might get replaced at a later date.
A variant of cardColumn designed for a single item.
Use this with a normal Element.column, Element.row or even a Element.el.
Chip
Chips have the same behavior as buttons but are visually less important.
In the official documentation chips have different names depending on where they are used:
- Input Chips are used inside a text field. Use
textInputfor this feature. - Choice Chips are used for selecting an option.
The material design guidelines recommend using
toggleButtonfor icons with no text and chips for text with no icons. - Filter Chips are used for selecting multiple options. They typically have a done-icon when selected.
- Action chips are like button. Make sure to include an icon when using action chips.
Technical Remark:
- Decided against the implementation of an outlined chip. Please open a new issue or a PR if you want to have it implemented.
A variant of textInput designed for Input.text.
A text input style that is included only to support input chips.
Technical Remark:
- This is just a temporary implementation. It will soon be replaced with the official implementation.

The material design comes with customizable color palettes.
Check out the official documentation about the color system to see how these colors are used.
