材料中的可扩展搜索栏，角度为 6

Question

我想添加像this 这样的扩展搜索栏。我尝试在我的 angular6 项目中使用此插件，但导入此插件后出现以下错误

请任何人帮助我。有没有其他类似的插件？或者这个错误是什么。我没有使用任何像 bootstrap 这样的框架，我只想使用 angular6 或 material 来实现它。请帮忙。

这是我想出的：

.html

<div class="search-container" [ngClass]="{'hasValue':hasValue}">
            <mat-form-field floatLabel="never" >
                <input matInput type="search" [(ngModel)]="term" 
              placeholder="Search&hellip;" autocomplete="off"
             (blur)="hasValue=term?true:false">
            </mat-form-field>
            <button type="button" class="searchIcon" mat-icon-button 
            (click)="hasValue=!hasValue">
              <mat-icon *ngIf="!hasValue" class="mat-18">search</mat-icon>
              <mat-icon *ngIf="hasValue" (click)="term=''" class="mat-18 
             ">close</mat-icon>
             </button>
        </div>

.ts

 term:string;
 hasValue:boolean;

.scss

.search-container{
max-width: 500px;
.mat-form-field{
  font-size:14px;
  line-height: 0.9em;
  -webkit-transition: width 0.4s ease-in-out;
  transition: width 0.4s ease-in-out;
  width: 0px;
}
}

.hasValue{
  .mat-form-field{
    width: 300px;
  }

  .searchIcon{
    background:#e2e9eb;
  }
}
