Components with a 'required' signalized input can not be dynamically created with createComponent about angular HOT 1 OPEN

Components with required inputs can be dynamically created, just make sure those inputs are set via .setInput() before the component is change detected.

Note that it's not possible to dynamically create an arbitrary component in a guaranteed correct way. Any component can have assumptions about how it'll be created:

• with certain DI providers available
• with certain inputs available (required inputs)
• what types of values it accepts for its inputs
• as a child of a specific other component
• with specific content children
• with a certain directive applied (not possible to do dynamically)

To correctly create a component, you need to meet these requirements. I don't think having the required status of inputs available via ComponentMirror is sufficient. For example, since you don't know the types of such inputs, how can you expect to provide values for them even if you know they're required?

The alternative is that you can not use signal inputs and stick with the old way.

Required inputs exist for non-signal inputs, too. If you fail to provide a value for one, the component will likely crash when it attempts to read it and gets an undefined value.
