Can you make showSearch() Dismissible?

Question

Is there a way to make the search dialog (showSearch()) Dismissible? I'd like to be able to swipe away the search page to close it.

He wrote code for detecting swiping left or right. Write navigation.pop() on which swipe u wanna close search page, with animation u can make it smoother

Answer 2

You could use swipedetector as a parent for the search page and use the function onSwipeLeft or onSwipeRight to close the page calling pop function https://pub.dev/documentation/swipedetector/latest/

There ya go

import 'package:flutter/material.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: MyHomePage(),
    );
  }
}

class MyHomePage extends StatefulWidget {
  final List<String> list = List.generate(10, (index) => "Text $index");

  MyHomePage({
    Key? key,
  }) : super(key: key);
  @override
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        centerTitle: true,
        title: Text('Search Bar'),
        actions: <Widget>[
          IconButton(
            onPressed: () {
              showSearch(context: context, delegate: Search(widget.list));
            },
            icon: Icon(Icons.search),
          )
        ],
      ),
      body: ListView.builder(
        itemCount: widget.list.length,
        itemBuilder: (context, index) => ListTile(
          title: Text(
            widget.list[index],
          ),
        ),
      ),
    );
  }
}

class Search extends SearchDelegate {
  @override
  List<Widget> buildActions(BuildContext context) {
    return <Widget>[
      IconButton(
        icon: Icon(Icons.close),
        onPressed: () {
          query = "";
        },
      ),
    ];
  }

  @override
  Widget buildLeading(BuildContext context) {
    return IconButton(
      icon: Icon(Icons.arrow_back),
      onPressed: () {
        Navigator.pop(context);
      },
    );
  }

  String selectedResult = "";

  @override
  Widget buildResults(BuildContext context) {
    return Container(
      child: Center(
        child: Text(selectedResult),
      ),
    );
  }

  final List<String> listExample;
  Search(this.listExample);

  List<String> recentList = ["Text 4", "Text 3"];

  @override
  Widget buildSuggestions(BuildContext context) {
    List<String> suggestionList = [];
    query.isEmpty
        ? suggestionList = recentList //In the true case
        : suggestionList.addAll(listExample.where(
            // In the false case
            (element) => element.contains(query),
          ));

    return GestureDetector(
      onPanUpdate: (details) {
        // Swiping in right direction.
        if (details.delta.dx > 0) {
          print('right');
          Navigator.pop(context);
        }

        // Swiping in left direction.
        if (details.delta.dx < 0) {
          print('left');
        }
      },
      child: Container(
        child: ListView.builder(
          itemCount: suggestionList.length,
          itemBuilder: (context, index) {
            return ListTile(
              title: Text(
                suggestionList[index],
              ),
              leading: query.isEmpty ? Icon(Icons.access_time) : SizedBox(),
              onTap: () {
                selectedResult = suggestionList[index];
                showResults(context);
              },
            );
          },
        ),
      ),
    );
  }
}

With that code you could drag from anywhere in the body
