# flutter_tags
[](https://pub.dartlang.org/packages/flutter_tags)
[](https://github.com/Solido/awesome-flutter#ui)
[](https://www.paypal.me/dnag88)
Create beautiful tags quickly and easily.
## Installing
Add this to your package's pubspec.yaml file:
```dart
dependencies:
flutter_tags: "^0.4.9+1"
```
## DEMO
<div align="center">
<table>
<tr>
<td style="text-align:center">
<img width = "250px" src="https://github.com/Dn-a/flutter_tags/raw/master/repo-file/img/example0.4.0_1.gif" />
</td>
<td style="text-align:center">
<img width = "250px" src="https://github.com/Dn-a/flutter_tags/raw/master/repo-file/img/example0.4.0_2.gif" />
</td>
</tr>
</table>
</div>
## Simple usage
```dart
import 'package:flutter_tags/flutter_tags.dart';
.
.
.
List _items;
double _fontSize = 14;
@override
void initState(){
super.initState();
// if you store data on a local database (sqflite), then you could do something like this
Model().getItems().then((items){
_items = items;
});
}
@override
Widget build(BuildContext context) {
return Tags(
key:_tagStateKey,
textField: TagsTextField(
textStyle: TextStyle(fontSize: _fontSize),
constraintSuggestion: true, suggestions: [],
//width: double.infinity, padding: EdgeInsets.symmetric(horizontal: 10),
onSubmitted: (String str) {
// Add item to the data source.
setState(() {
// required
_items.add(str);
});
},
),
itemCount: _items.length, // required
itemBuilder: (int index){
final item = _items[index];
return ItemTags(
// Each ItemTags must contain a Key. Keys allow Flutter to
// uniquely identify widgets.
key: Key(index.toString()),
index: index, // required
title: item.title,
active: item.active,
customData: item.customData,
textStyle: TextStyle( fontSize: _fontSize, ),
combine: ItemTagsCombine.withTextBefore,
image: ItemTagsImage(
image: AssetImage("img.jpg") // OR NetworkImage("https://...image.png")
), // OR null,
icon: ItemTagsIcon(
icon: Icons.add,
), // OR null,
removeButton: ItemTagsRemoveButton(
onRemoved: (){
// Remove the item from the data source.
setState(() {
// required
_items.removeAt(index);
});
//required
return true;
},
), // OR null,
onPressed: (item) => print(item),
onLongPressed: (item) => print(item),
);
},
);
}
final GlobalKey<TagsState> _tagStateKey = GlobalKey<TagsState>();
// Allows you to get a list of all the ItemTags
_getAllItem(){
List<Item> lst = _tagStateKey.currentState?.getAllItem;
if(lst!=null)
lst.where((a) => a.active==true).forEach( ( a) => print(a.title));
}
```
## Wrapped widget example
You are free to wrap ItemTags () inside another widget
```dart
Tags(
itemCount: items.length,
itemBuilder: (int index){
return Tooltip(
message: item.title,
child:ItemTags(
title:item.title,
)
);
},
);
```

# Launch Screen Assets
You can customize the launch screen with your own desired assets by replacing the image files in this directory.
You can also do it by opening your Flutter project's Xcode project with `open ios/Runner.xcworkspace`, selecting `Runner/Assets.xcassets` in the Project Navigator and dropping in the desired images.

description: A new Flutter application.
# The following defines the version and build number for your application.
# A version number is three numbers separated by dots, like 1.2.43
# followed by an optional build number separated by a +.
# Both the version and the builder number may be overridden in flutter
# build by specifying --build-name and --build-number, respectively.
# Read more about versioning at semver.org.

# The following adds the Cupertino Icons font to your application.
# Use with the CupertinoIcons class for iOS style icons.
cupertino_icons: ^0.1.2

sdk: flutter
# For information on the generic Dart part of this file, see the
# following page: https://www.dartlang.org/tools/pub/pubspec
# The following section is specific to Flutter.
flutter:
# The following line ensures that the Material Icons font is
# included with your application, so that you can use the icons in
# the material Icons class.
uses-material-design: true
# To add assets to your application, add an assets section, like this:
assets:
- img/p1.jpg
- img/p2.jpg
- img/p3.jpg
- img/p4.jpg
# An image asset can refer to one or more resolution-specific "variants", see
# https://flutter.io/assets-and-images/#resolution-aware.
# For details regarding adding assets from package dependencies, see
# https://flutter.io/assets-and-images/#from-packages
# To add custom fonts to your application, add a fonts section here,
# in this "flutter" section. Each entry in this list should have a
# "family" key with the font family name, and a "fonts" key with a
# list giving the asset and other descriptors for the font. For
# example:
# fonts:
# - family: Schyler
# fonts:
# - asset: fonts/Schyler-Regular.ttf
# - asset: fonts/Schyler-Italic.ttf
# style: italic
# - family: Trajan Pro
# fonts:
# - asset: fonts/TrajanPro.ttf
# - asset: fonts/TrajanPro_Bold.ttf
# weight: 700
