Flutter (Dart) How to add copy to clipboard on tap to a app?
I'm a beginner to Flutter and I just started following their Name Generator app tutorial and made a simple name generating app. I'm wondering if it's possible to add copy to clipboard feature when a user tap on a name? I tried to implement a solution I found on stack but it didn't work. My full code is here. Any advise is appreciated.
import 'package:flutter/material.dart';
import 'package:english_words/english_words.dart';
void main() => runApp(new MyApp());
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return new MaterialApp(
title: 'Startup Name Generator',
home: new RandomWords(),
);
}
}
class RandomWords extends StatefulWidget {
@override
RandomWordsState createState() => new RandomWordsState();
}
class RandomWordsState extends State<RandomWords> {
final List<WordPair> _suggestions = <WordPair>[];
final Set<WordPair> _saved = new Set<WordPair>();
final TextStyle _biggerFont = const TextStyle(fontSize: 18.0);
@override
Widget build(BuildContext context) {
return new Scaffold(
appBar: new AppBar(
title: const Text('Startup Name Generator'),
actions: <Widget>[
new IconButton(icon: const Icon(Icons.list), onPressed: _pushSaved),
],
),
body: _buildSuggestions(),
);
}
Widget _buildSuggestions() {
return new ListView.builder(
padding: const EdgeInsets.all(16.0),
itemBuilder: (BuildContext _context, int i) {
if (i.isOdd) {
return const Divider();
}
final int index = i ~/ 2;
if (index >= _suggestions.length) {
_suggestions.addAll(generateWordPairs().take(10));
}
return _buildRow(_suggestions[index]);
});
}
Widget _buildRow(WordPair pair) {
final bool alreadySaved = _saved.contains(pair);
return new ListTile(
title: new Text(
pair.asPascalCase,
style: _biggerFont,
),
trailing: new Icon(
alreadySaved ? Icons.favorite : Icons.favorite_border,
color: alreadySaved ? Colors.red : null,
),
onTap: () {
setState(() {
if (alreadySaved) {
_saved.remove(pair);
} else {
_saved.add(pair);
}
});
},
);
}
void _pushSaved() {
Navigator.of(context).push(
new MaterialPageRoute<void>(
builder: (BuildContext context) {
final Iterable<ListTile> tiles = _saved.map(
(WordPair pair) {
return new ListTile(
title: new Text(
pair.asPascalCase,
style: _biggerFont,
),
);
},
);
final List<Widget> divided = ListTile
.divideTiles(
context: context,
tiles: tiles,
)
.toList();
return new Scaffold(
appBar: new AppBar(
title: const Text('Saved Suggestions'),
),
body: new ListView(children: divided),
);
},
),
);
}
}
import:
import 'package:flutter/services.dart';
And then Simply implement this:
onTap: () {
Clipboard.setData(ClipboardData(text: "your text"));
},
If you want better solution without any dependency that working async use this:
import 'package:flutter/services.dart';
Clipboard.setData(new ClipboardData(text: email)).then((_){
ScaffoldMessenger.of(context).showSnackBar(SnackBar(content: Text("Email address copied to clipboard")));
});
There was breaking changes that you might find useful in the following link: https://docs.flutter.dev/release/breaking-changes/scaffold-messenger
You can use the Flutter clipboard_manager package: Flutter clipboard manager
To install it, follow the instructions on this page, pretty straightforward: Flutter clipboard manager installation process
To use it, import it in the .dart file you're writing and then you can use this: ClipboardManager.copyToClipBoard("your text to copy")
Where "your text to copy" can be substituted by any string you want to copy to the clipboard.
If you want to create a snackbar after copying the text, since it's async you can do:
ClipboardManager.copyToClipBoard("your text to copy").then((result) {
final snackBar = SnackBar(
content: Text('Copied to Clipboard'),
action: SnackBarAction(
label: 'Undo',
onPressed: () {},
),
);
Scaffold.of(context).showSnackBar(snackBar);
});
Adendum: If you look at the package source code what it basically does is this:
Clipboard.setData(ClipboardData(text: "your text to copy"));
However, I find that the extra bit of syntactic sugar and the advantage of being async makes it a better solution, nothing you can't do with vanilla Flutter, but I find it a bit better.
