The base class for all web widgets. Override this class to create a custom
widget type, or use one of the default types which covers most common use
cases.
A Route defines a destination in Serverpod's web server. It will handle
a call and generate an appropriate response by manipulating the
HttpRequest object. You override Route, or more likely it's subclass
WidgetRoute to create your own custom routes in your server.
A widget based on a HTML template. The name of the template should
correspond to a template file in your server's web/templates directory.
Set the custom values of the template by populating the values field. If
values are set that aren't Strings, the toString method will be called
on the value. The templates are loaded when the server starts. If you add
new templates or modify existing templates, you will need to restart the
server for them to take effect.
