renderAndGetDom function
Element?
renderAndGetDom(
- dynamic component, {
- bool autoTearDown = true,
- Callback? autoTearDownCallback,
Renders a React component or builder into a detached node and returns the associated DOM node.
By default the rendered instance will be unmounted after the current test, to prevent this behavior set
autoTearDown
to false.
If
component
is a function component, calling renderAndGetDom will throw aStateError
.See
TestJacket.getNode
for more information about this limitation.
Implementation
Element? renderAndGetDom(dynamic component, {bool autoTearDown = true, Callback? autoTearDownCallback}) {
final renderedInstance = render(component, autoTearDown: autoTearDown, autoTearDownCallback: autoTearDownCallback);
if (!react_test_utils.isCompositeComponent(renderedInstance) && !react_test_utils.isDOMComponent(renderedInstance)) {
throw StateError(
'renderAndGetDom() is only supported when the rendered object is a DOM or composite (class based) component.');
}
return findDomNode(renderedInstance);
