ODS Flutter library 0.8.0

[Tayebsed93]

ODS Flutter library v0.8.0 is here!

Be careful, this version includes several library API changes in order to prepare the v1.0 release.

New components

• Segmented Button : A group of toggle buttons. Only one option in a group of toggle buttons can be selected and active at a time. Selecting one option deselects any other. Use for simple choices between two to five items (for more items or complex choices, use chips)

• Icon Button : Each icon button has as an optional toggle behavior, which gives the button a selected and unselected state. Toggle buttons remain highlighted when selected, and are styled differently than the default icon buttons.

There are four styles of icon buttons: Filled icon button, Filled tonal icon button, Outlined icon button and Standard icon button

• Vertical Header First Card : This is a full width card containing elements arranged vertically with a header (thumbnail, title & subtitle) as first element.
  

• Navigation Rail : This is a full width card containing elements arranged vertically with an image as first element.

New Module

• Lists : Lists are continuous, vertical indexes of text and images
