Thanks for helping me @Shamnad_KS .
PFB the solution.
1: Add a formGroup custom property in FORM component like this Key:[formGroup] and Value: page.formName
2: Add formControlName custom property for the Input fields.
Eg: formControlName = firstName
3: Use a dependency node in the onInit flow to import @angular/forms.
4: Use script Node in onInit Flow to create a new form group.
Now we can access the user inputs inside flow via the page object.
