title: what do @pragma("vm:prefer-inline") mean in Flutter?
body: <p>When I studied framework code, I found that there was a lot of code in the following form：</p>
  <p><code>@pragma(&quot;vm:entry-point&quot;, &quot;call&quot;)</code>
  <code>@pragma(&quot;vm:entry-point&quot;, &quot;set&quot;)</code>
  <code>@pragma(&quot;vm:entry-point&quot;, &quot;get&quot;)</code>
  <code>@pragma(&quot;vm:prefer-inline&quot;)</code>
  ......</p>
  <p>What do these mean?</p>
