Jetpack Compose AppCard in Wear Material

Opinionated Wear Material Card that offers a specific 5 slot layout to show information about an application, e.g. a notification. AppCards are designed to show interactive elements from multiple applications. They will typically be used by the system UI, e.g. for showing a list of notifications from different applications. However it could also be adapted by individual application developers to show information about different parts of their application.

The first row of the layout has three slots, 1) a small optional application Image or Icon of size CardDefaults.AppImageSizexCardDefaults.AppImageSize dp, 2) an application name (emphasised with the CardColors.appColor() color), it is expected to be a short start aligned Text composable, and 3) the time that the application activity has occurred which will be shown on the top row of the card, this is expected to be an end aligned Text composable showing a time relevant to the contents of the Card.

The second row shows a title, this is expected to be a single row of start aligned Text.

The rest of the Card contains the content which can be either Text or an Image. If the content is text it can be single or multiple line and is expected to be Top and Start aligned.

If more than one composable is provided in the content slot it is the responsibility of the caller to determine how to layout the contents, e.g. provide either a row or a column.

Example of an AppCard with icon, title, time and two lines of body text:

Parameters

Name	Description
`onClick`	Will be called when the user clicks the card
`appName`	A slot for displaying the application name, expected to be a single line of start aligned text of Typography.title3
`time`	A slot for displaying the time relevant to the contents of the card, expected to be a short piece of end aligned text.

`appImage`	A slot for a small (CardDefaults.AppImageSizexCardDefaults.AppImageSize ) Image associated with the application.
`backgroundPainter`	A painter used to paint the background of the card. A card will normally have a gradient background. Use CardDefaults.cardBackgroundPainter() to obtain an appropriate painter
`contentColor`	The default color to use for content() slot unless explicitly set.
