Generic type ‘ɵɵcomponentdeclaration’ requires between 7 and 8 type arguments.

        ERROR: Generic type 'ɵɵcomponentDeclaration' requires between 7 and 8 type arguments.
        

DESCRIPTION: This error occurs when declaring a component using the Angular Compiler's component factory function (ɵɵcomponentDeclaration) with an incorrect number of type arguments.

SOLUTION: To resolve this error, you need to make sure that you provide the correct number of type arguments when declaring the component.

EXAMPLE: Let's assume you have the following component defined in your Angular application:

          // app.component.ts
          import { Component } from '@angular/core';
          
          @Component({
            selector: 'app-root',
            template: `
              

Welcome to My App

` }) export class AppComponent { // component logic here }

To declare this component using the Angular Compiler's component factory function (ɵɵcomponentDeclaration),
you should provide the correct type arguments as follows:


          // app.component.factory.ts
          import { ɵɵcomponentDeclaration } from '@angular/core';
          import { AppComponent } from './app.component';
          
          export function AppComponent_Factory() {
            return ɵɵcomponentDeclaration({
              type: AppComponent,
              selectors: [['app-root']],
              factory: () => new AppComponent(),
              template: () => { /* component template */ },
              styles: [] // component styles
            });
          }
        

In the above example, we are providing all the required type arguments:
- type: The type of the component (AppComponent).
- selectors: The selectors used to identify the component (in this case, ['app-root']).
- factory: A factory function that creates an instance of the component.
- template: A function that returns the component's template.
- styles: An array of CSS styles applied to the component.

Make sure to adjust the type arguments based on your component's structure and needs.
