How can I set default selected last button in toggle group.
This is my code.

<mat-button-toggle-group #group="matButtonToggleGroup">
    <mat-button-toggle value="Heritage">
        <span>Heritage</span>
    </mat-button-toggle>
    <mat-button-toggle value="Nature">
        <span>Nature</span>
    </mat-button-toggle>
    <mat-button-toggle value="People">
        <span>People</span>
    </mat-button-toggle>
    <mat-button-toggle value="All">
        <span>All</span>
    </mat-button-toggle>
</mat-button-toggle-group>

Answer

I fixed it. Simply add the value attribute to the mat-button-toggle-group tag.

<mat-button-toggle-group #group="matButtonToggleGroup" value="All">
<mat-button-toggle value="Heritage">
    <span>Heritage</span>
</mat-button-toggle>
<mat-button-toggle value="Nature">
    <span>Nature</span>
</mat-button-toggle>
<mat-button-toggle value="People">
    <span>People</span>
</mat-button-toggle>
<mat-button-toggle value="All">
    <span>All</span>
</mat-button-toggle>
