How to bind default value in mat-radio-group angular reactive forms : <p>In my case it needs to active option 01 as default selection. It is working with checked=true property, but value is not binding with the formControlName="options", it is binding when user select any option. if no any user selection options value shows as "null".</p>



<pre class="lang-html prettyprint-override"><code>  &lt;div class="row"&gt;
      &lt;mat-radio-group formControlName="options"&gt;
        &lt;mat-radio-button checked=true  value="1"&gt;Option 01&lt;/mat-radio-button&gt;
        &lt;mat-radio-button  value="2"&gt;Option 02&lt;/mat-radio-button&gt;
      &lt;/mat-radio-group&gt;
    &lt;/div&gt;
</code></pre>

<p>Please kindly help me to resolve this issue. Thank you.</p>
