Calling Firebase `validatePassword` outside of an Injection context

从 validatePassword 入口点和所示的 runInInjectionContext 包装器开始，然后跟踪 AngularFire 如何处理 Auth 实例和注入上下文。确定该警告是否符合预期，以及是否需要这个包装器；完成标准是记录正确的调用模式，或在不产生警告的情况下简化验证。

Is the running outside of injection context warning legitimate when using validatePassword?

My code:

import { EnvironmentInjector, inject, runInInjectionContext } from '@angular/core';
import { Auth, validatePassword } from '@angular/fire/auth';
import type { PasswordValidationStatus } from '@angular/fire/auth';
import type { AbstractControl, AsyncValidatorFn, ValidationErrors } from '@angular/forms';

import { getPasswordControlValue } from './util';

/**
 * Validate against the Firebase Project Authentication Password Policy.
 *
 * Note: at this time there is no actual need for this because the policy only enforces length and
 * other Validators already check for that. However it is nice to know how to do this.
 */
export const passwordFirebaseValidator = (): AsyncValidatorFn => {
  const auth: Auth = inject(Auth);
  const environmentInjector = inject(EnvironmentInjector);

  return async (control: AbstractControl<unknown>): Promise<ValidationErrors | null> => {
    const value = getPasswordControlValue(control);

    // Like Validators.email, rely on Validators.required to check for blank passwords.
    if (value == undefined) {
      return null; // eslint-disable-line unicorn/no-null -- ValidatorFn returns null
    }

    const { passwordPolicy: _, ...status } = await runInInjectionContext(
      environmentInjector,
      async (): Promise<PasswordValidationStatus> => validatePassword(auth, value),
    );

    return status.isValid ? null : { firebasevalidator: status }; // eslint-disable-line unicorn/no-null
  };
};

I added EnvironmentInjector and runInInjectionContext and that got rid of the warning, but is all this necessary? It would be nice if validation was simplier.
