How can I create custom form controls in Angular Material?

You can create custom form controls in Angular Material by extending the existing components and implementing ControlValueAccessor.

Can you give me a code example of a custom input control?

Sure! Here's a simple example:

import { Component, forwardRef } from '@angular/core';
import { ControlValueAccessor, NG_VALUE_ACCESSOR } from '@angular/forms';

@Component({
  selector: 'app-custom-input',
  template: `<input [(ngModel)]="value" (input)="onChange(value)" />`,
  providers: [{
    provide: NG_VALUE_ACCESSOR,
    useExisting: forwardRef(() => CustomInputComponent),
    multi: true
  }]
})
export class CustomInputComponent implements ControlValueAccessor {
  value: string;
  onChange = (value: string) => {};
  onTouched = () => {};

  writeValue(value: string): void {
    this.value = value;
  }

  registerOnChange(fn: any): void {
    this.onChange = fn;
  }

  registerOnTouched(fn: any): void {
    this.onTouched = fn;
  }
}

What are the benefits of using custom form controls?

Custom form controls allow for better encapsulation, reusability, and can be tailored to meet specific design requirements.
