ZBuild

The special <ZBuild> tag allows to inject widgets that are rendered in the "native" way - into the ZML.

It has two variants:

• Build the widget by invoking a bound method.
• Build the widget by invoking a builder function.

Invoking Bound Method

We can use the z-build attribute to invoke a bound method that will return a Widget.

Example

Builder Function

Alternatively, we can use the z-builder attribute to provide a builder function.

Example

When using this variation, the z-builder expects a Dart expression that evaluates to Widget?.

If the expression evaluates to null - nothing is rendered (not even an empty Container).
