angular – 如何制作可滚动的mat-list

我正在尝试使用Angular 4.4.6和Angular Material 2.0.0-beta.12在响应高度容器内构建@L_781_0@mat-list.如何在不溢出父容器的情况下使mat-list可滚动？

:host{
  border: 3px dashed red;
  width: 100%;
  min-height: 150px;
  max-height: 350px;
  height: 10%;
  display: flex;
  flex-direction: column;
  mat-toolbar {
    flex-grow: 0;
  }
  mat-list {
    flex-grow: 1;
    border: 3px solid green;
  }
}
