如何为matStepperNext创建条件？

import { MatStepperModule } from '@angular/material/stepper';
import { MatStepperNextModule } from '@angular/material/stepper-next';

<mat-horizontal-stepper>
  <mat-step>
    <!-- 步骤内容 -->
    <ng-template matStepLabel>步骤1</ng-template>
    <!-- 输入表单 -->
    <mat-form-field>
      <input matInput placeholder="输入内容">
    </mat-form-field>
    <!-- 下一步按钮 -->
    <button matStepperNext *ngIf="isValidStep1()">下一步</button>
  </mat-step>
  <mat-step>
    <!-- 步骤内容 -->
    <ng-template matStepLabel>步骤2</ng-template>
    <!-- 输入表单 -->
    <mat-form-field>
      <input matInput placeholder="输入内容">
    </mat-form-field>
    <!-- 下一步按钮 -->
    <button matStepperNext *ngIf="isValidStep2()">下一步</button>
  </mat-step>
  <!-- 其他步骤... -->
</mat-horizontal-stepper>
