buildSuggestions method

Widget buildSuggestions (BuildContext context)

<span class="feature">override</span>

<p>Suggestions shown in the body of the search page while the user types a query into the search field.</p> <p>The delegate method is called whenever the content of <a href="https:api.flutter.dev/flutter/material/SearchDelegate/query.html">query</a> changes. The suggestions should be based on the current <a href="https:api.flutter.dev/flutter/material/SearchDelegate/query.html">query</a> string. If the query string is empty, it is good practice to show suggested queries based on past queries or the current context.</p> <p>Usually, this method will return a <a href="https:api.flutter.dev/flutter/widgets/ListView-class.html">ListView</a> with one <a href="https:api.flutter.dev/flutter/material/ListTile-class.html">ListTile</a> per suggestion. When <a href="https:api.flutter.dev/flutter/material/ListTile/onTap.html">ListTile.onTap</a> is called, <a href="https:api.flutter.dev/flutter/material/SearchDelegate/query.html">query</a> should be updated with the corresponding suggestion and the results page should be shown by calling <a href="https:api.flutter.dev/flutter/material/SearchDelegate/showResults.html">showResults</a>.</p>
