<p>Fact-checks are represented by <a href="/constructor/factCheck">factCheck</a> constructors, optionally contained in the <code>factcheck</code> field of the <a href="/constructor/message">message</a> constructor. </p>
<p>Fact-checks are represented by <a href="/constructor/factCheck">factCheck</a> constructors, contained in the <code>factcheck</code> field of the <a href="/constructor/message">message</a> constructor. </p>
<p>Sometimes (i.e. for performance reasons), even if a message <em>does</em> have a factcheck, it may not be returned in the <code>text</code> field of the <a href="/constructor/factCheck">factCheck</a> associated to the <a href="/constructor/message">message</a>: in this case, the <a href="/constructor/factCheck">factCheck</a>.<code>need_check</code> flag will be set and the <code>country</code>/<code>text</code> flags won't be set, and the client should request the full text of the fact check manually using <a href="/method/messages.getFactCheck">messages.getFactCheck</a> when the message scrolls into view. </p>
<p>These manual requests should be bundled: every time a new ID is added to the queue of factchecks to manually fetch, postpone fetching by 80ms. </p>
<p>Store all <em>full</em> (i.e. those with a <code>country</code>/<code>text</code>) factchecks in a local database, using the <code>hash</code> as key.<br>
Avoid fetching <em>min</em> (i.e. those where <code>need_check</code> is set) factchecks if a factcheck with the same <code>hash</code> is already cached in the local database. </p>
<p>Example implementation: <a href="https://github.com/DrKLO/Telegram/blob/5fa5549a4a7f48476be29cc0facf68990ea10f62/TMessagesProj/src/main/java/org/telegram/messenger/FactCheckController.java">android</a>.</p>
