VxConditional class

Runs a WidgetBuilder's result if the condition is true.

When condition is true the builder is run. If false and fallback is not null, fallback is run. If fallback is null and condition is false, an empty Container is rendered.

Example:

VxConditional(
 condition: true,
builder: (context) {
   return Text('This gets rendered');
 },
)

VxConditional(
 condition: false,
 builder: (context) {
   return Text('This does not get rendered, an empty offstage will be rendered');
 },
)

VxConditional(
 condition: false,
 builder: (context) {
   return Text('This does not get rendered, as fallback is not null, it is used to render the fallback widget.');
 },
 fallback: (context) {
   return Text('This gets rendered');
 }
)
