我从 StackBlitz 复制了相同的代码，但材料日期范围选择器在我的应用程序中不起作用。

这是我正在使用的确切代码：

<mat-form-field appearance="fill">
  <mat-label>Enter a date range</mat-label>
  <mat-date-range-input [rangePicker]="picker">
    <input matStartDate placeholder="Start date">
    <input matEndDate placeholder="End date">
  </mat-date-range-input>
  <mat-datepicker-toggle matSuffix [for]="picker"></mat-datepicker-toggle>
  <mat-date-range-picker #picker></mat-date-range-picker>
</mat-form-field>

这就是它的样子......它只是一个输入字段，但没有可供选择的数据范围选择器

在此处输入图像描述

我希望能够选择范围选择器并让用户选择数据范围。
