Missing documentation for controlsConfig argument of FormBuilder.group method #43984

By the way, the correct way to use both formBuilder.group({
foo: [
{
value: 'Foo',
disabled: true,
},
{
updateOn: 'blur',
},
],
});However, it was quite unintuitive to figure out. The fact that you have to use an array with two objects is just incomprehensible. I would suggest to update the documentation to make this case explicit and I would also suggest to update the API and typing declarations as well to make it more straightforward to use. |

Also, the code here is just misleading:
It should be: const validatorOrOpts: (
| ValidatorFn
| ValidatorFn[]
| AbstractControlOptions
| null
) = (controlConfig[1] || null);because the second argument could be either validator, array of validators or an options object. |

Description
The documentation for
FormBuilder.group()method lacks proper description of thecontrolsConfigargument.It is described the following way:
and is typed this way:
{ [key: string]: any; }.However, it's not clear what is the interface of the object values. The typing declarations are also missing in the code of this method.
I can't figure out how to use
updateOn,valueanddisabledoptions at the same time with the form builder and it's not possible to understand from the documentation or type declarations.What is the affected URL?
https://angular.io/api/forms/FormBuilder#group
