Description:

sup

'sup
A Flutter widget which displays an image, a title, and a subtitle for errors, empty states, or just fancy custom messages.

Getting Started #
Follow the installation instructions.
QuickSup #
Use QuickSup to quickly show standard errors and empty states, fast and easy.
Ideal for when you want to avoid spending time on your UI messages but want a bit more than a Text widget.
QuickSup.error(
title: 'Nope',
subtitle: 'That didn\'t work, son.',
onRetry: () {},
);
copied to clipboard
QuickSup.empty(
subtitle: 'No items in this list',
);
copied to clipboard
SupConfigurator #
If you want to customize, one place to do that is SupConfigurator.
This is an InheritedWidget that hosts a default SupConfig wherever you place it in your widget tree. Sup widgets then access the nearest SupConfigurator and render themselves accordingly.
MaterialApp(
title: 'My App',
home: SupConfigurator(
defaults: SupConfig(
alignment: SupAlignment.start,
),
child: myAppContent
),
);
copied to clipboard
Sup.from (Config/Templates) #
If you are going to have different Sup configurations, such as specific errors, specific empty states, hints, etc., this is for you.
Define a SupConfig instance somewhere in your codebase, then pass it to Sup using Sup.from. That's all. You can pass specific override params too.
Sup.from(MySupConfigs.sendError);
Sup.from(
MySupConfigs.noSearchResults,
subtitle: 'No results found for $query',
);
Sup.from(MySupConfigs.notEnoughEncouragement);
copied to clipboard
Sup Constructor #
Finally, you can also just create a new Sup instance using the constructor.
Sup(
image: Image(...),
title: Text('Hey'),
subtitle: Text('Welcome to the app'),
...
);
copied to clipboard
Configuration Order #
The order in which Sup applies configurations is the following:

Package defaults (see SupDefaults)
User defaults (SupConfigurator)
Sup.from
Sup parameters
