attribute and <code>[SupplyParameterFromQuery]</code> attribute. For example:</p>
<pre class="code" language="razor">@page "/query-parameters"

&lt;div&gt;Param1: @Param1&lt;/div&gt;

@code {
    [SupplyParameterFromQuery]
    [Parameter]
    public bool Param1 { get; set; }
}</pre>
<p>In case of the requested URL does not contain the parameter, Blazor Server will assume the value of that parameter as the value of <code>default</code> keyword of the respective type.</p>
