Streamline UI

[spezian]

Sometimes there are inconsistencies within widgets (like padding, ...) which should be the same and sometimes we implement similar things multiple times.

For example often widgets have this structure on top of a card:

• Leading (often title)
• Trailing
• Subtitle or some custom content
• Footer

ListTile is supposed to be only used for content which is max. 3 Lines and sometimes it's too limiting.

There are also other things which we can streamline, like the padding to the edge of the screen.
