another_flushbar 1.12.30 another_flushbar: ^1.12.30 copied to clipboard
A flexible widget for user notification. Customize your text, button, duration, animations and much more. For Android devs, it is made to replace Snackbars and Toasts.
another_flushbar #
Use this package if you need more customization when notifying your user. For Android developers, it is made to substitute toasts and snackbars. IOS developers, I don't know what you use there, but you will like it.
See the install instructions.
Quick reference #
Since customization requires a lot of properties, here is a quick cheatsheet:
Property | What does it do |
---|---|
title | The title displayed to the user |
titleColor | The title color displayed to the user |
titleSize | The title size displayed to the user |
message | The message displayed to the user. |
messageColor | The message color displayed to the user. |
messageSize | The message size displayed to the user. |
titleText | Replaces [title]. Although this accepts a [widget], it is meant to receive [Text] or [RichText] |
messageText | Replaces [message]. Although this accepts a [widget], it is meant to receive [Text] or [RichText] |
icon | You can use any widget here, but I recommend [Icon] or [Image] as indication of what kind of message you are displaying. Other widgets may break the layout |
shouldIconPulse | An option to animate the icon (if present). Defaults to true. |
maxWidth | Used to limit Flushbar width (usually on large screens) |
margin | Adds a custom margin to Flushbar |
padding | Adds a custom padding to Flushbar. The default follows material design guide line |
borderRadius | Adds a radius to specified corners of Flushbar. Best combined with [margin]. I do not recommend using it with [showProgressIndicator] or [leftBarIndicatorColor] |
textDirection | [TextDirection.ltr] by default. [Directionality.of(context)] to know whether it would be [TextDirection.ltr] or [TextDirection.rtl] |
borderColor | Adds a border to every side of Flushbar. I do not recommend using it with [showProgressIndicator] or [leftBarIndicatorColor] |
borderWidth | Changes the width of the border if [borderColor] is specified |
backgroundColor | Flushbar background color. Will be ignored if [backgroundGradient] is not null. |
leftBarIndicatorColor | If not null, shows a left vertical bar to better indicate the humor of the notification. It is not possible to use it with a [Form] and I do not recommend using it with [LinearProgressIndicator]. |
boxShadows | The shadows generated by Flushbar. Leave it null if you don't want a shadow. You can use more than one if you feel the need. Check this example |
backgroundGradient | Flushbar background gradient. Makes [backgroundColor] be ignored. |
mainButton | Use if you need an action from the user. [FlatButton] is recommended here. |
onTap | A callback that registers the user's click anywhere. An alternative to [mainButton] |
duration | How long until Flushbar will hide itself (be dismissed). To make it indefinite, leave it null. |
isDismissible | Determines if the user can swipe or click the overlay (if [routeBlur] > 0) to dismiss. It is recommended that you set [duration] != null if this is false. If the user swipes to dismiss or clicks the overlay, no value will be returned. |
dismissDirection | FlushbarDismissDirection.VERTICAL by default. Can also be [FlushbarDismissDirection.HORIZONTAL] in which case both left and right dismiss are allowed. |
flushbarPosition | Flushbar can be based on [FlushbarPosition.TOP] or on [FlushbarPosition.BOTTOM] of your screen. [FlushbarPosition.BOTTOM] is the default. |
flushbarStyle | Flushbar can be floating or be grounded to the edge of the screen. If grounded, I do not recommend using [margin] or [borderRadius]. [FlushbarStyle.FLOATING] is the default |
forwardAnimationCurve | The [Curve] animation used when show() is called. [Curves.easeOut] is default. |
reverseAnimationCurve | The [Curve] animation used when dismiss() is called. [Curves.fastOutSlowIn] is default. |
animationDuration | Use it to speed up or slow down the animation duration |
showProgressIndicator | true if you want to show a [LinearProgressIndicator]. If [progressIndicatorController] is null, an infinite progress indicator will be shown |
progressIndicatorController | An optional [AnimationController] when you want to control the progress of your [LinearProgressIndicator]. You are responsible for controlling the progress |
progressIndicatorBackgroundColor | a [LinearProgressIndicator] configuration parameter. |
progressIndicatorValueColor | a [LinearProgressIndicator] configuration parameter. |
barBlur | Default is 0.0. If different than 0.0, blurs only Flushbar's background. To take effect, make sure your [backgroundColor] has some opacity. The greater the value, the greater the blur. |
blockBackgroundInteraction | Determines if user can interact with the screen behind it. If this is false, [routeBlur] and [routeColor] will be ignored |
routeBlur | Default is 0.0. If different than 0.0, creates a blurred overlay that prevents the user from interacting with the screen. The greater the value, the greater the blur. It does not take effect if [blockBackgroundInteraction] is false |
routeColor | Default is [Colors.transparent]. Only takes effect if [routeBlur] > 0.0. Make sure you use a color with transparency e.g. Colors.grey[600].withOpacity(0.2) . It does not take effect if [blockBackgroundInteraction] is false |
userInputForm | A [TextFormField] in case you want a simple user input. Every other widget is ignored if this is not null. |
onStatusChanged | a callback for you to listen to the different Flushbar status |
Quick tip
If you use a lot of those properties, it makes sense to make a factory to help with your Flushbar's base appearance. Things like shadows, padding, margins, text styles usually don't change within the app. Take a look at FlushbarHelper class and use it as an example.
We are on YouTube! #
While studying Flutter I stumbled on two amazing tutorials on how to use Flushbar. Make sure you show those guys some love.
- A beginners tutorial by Matej Rešetár
- A more advanced usage by Javier González Rodríguez
Getting Started #
The examples bellow were updated for version 1.3.0. Changes might have been made. See the changelog if any of the examples do not reflect Flushbar's current state.
The possibilities #
A basic Flushbar #
The most basic Flushbar uses only a message. Failing to provide it before you call show()
will result in a runtime error.
Duration
, if not provided, will create an infinite Flushbar, only dismissible by code, back button clicks, or a drag (case isDismissible
is set to true
).
- Note that only
message
is a required parameter. All the other ones are optional
class YourAwesomeApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'YourAwesomeApp',
home: Scaffold(
Container(
child: Center(
child: MaterialButton(
onPressed: (){
Flushbar(
title: "Hey Ninja",
message: "Lorem Ipsum is simply dummy text of the printing and typesetting industry",
duration: Duration(seconds: 3),
)..show(context);
},
),
),
),
),
);
}
}
Lets get crazy Flushbar #
Here is how customized things can get.
Flushbar(
title: "Hey Ninja",
titleColor: Colors.white,
message: "Lorem Ipsum is simply dummy text of the printing and typesetting industry",
flushbarPosition: FlushbarPosition.TOP,
flushbarStyle: FlushbarStyle.FLOATING,
reverseAnimationCurve: Curves.decelerate,
forwardAnimationCurve: Curves.elasticOut,
backgroundColor: Colors.red,
boxShadows: [BoxShadow(color: Colors.blue[800], offset: Offset(0.0, 2.0), blurRadius: 3.0)],
backgroundGradient: LinearGradient(colors: [Colors.blueGrey, Colors.black]),
isDismissible: false,
duration: Duration(seconds: 4),
icon: Icon(
Icons.check,
color: Colors.greenAccent,
),
mainButton: FlatButton(
onPressed: () {},
child: Text(
"CLAP",
style: TextStyle(color: Colors.amber),
),
),
showProgressIndicator: true,
progressIndicatorBackgroundColor: Colors.blueGrey,
titleText: Text(
"Hello Hero",
style: TextStyle(
fontWeight: FontWeight.bold, fontSize: 20.0, color: Colors.yellow[600], fontFamily: "ShadowsIntoLightTwo"),
),
messageText: Text(
"You killed that giant monster in the city. Congratulations!",
style: TextStyle(fontSize: 18.0, color: Colors.green, fontFamily: "ShadowsIntoLightTwo"),
),
);
- Don't forget to call
show()
or the bar will stay hidden. - To deactivate any of those properties, pass
null
to it.
Styles #
Flushbar can be either floating or grounded to the edge of the screen.
I don't recommend using margin
or borderRadius
if you chose FlushbarStyle.GROUNDED
style.
Flushbar(flushbarStyle: FlushbarStyle.FLOATING)
or
Flushbar(flushbarStyle: FlushbarStyle.GROUNDED)
Floating Style | Grounded Style |
---|---|
Padding and Border Radius #
You can give it some padding and a border radius. Works best with FlushbarStyle.FLOATING
Flushbar(
margin: EdgeInsets.all(8),
borderRadius: BorderRadius.circular(8),
);
Left indicator bar #
Flushbar has a lateral bar to better convey the humor of the notification. To use it, simple give leftBarIndicatorColor
a color.
Flushbar(
message: "Lorem Ipsum is simply dummy text of the printing and typesetting industry",
icon: Icon(
Icons.info_outline,
size: 28.0,
color: Colors.blue[300],
),
duration: Duration(seconds: 3),
leftBarIndicatorColor: Colors.blue[300],
)..show(context);
Customize your text #
If you need a more fancy text, you can use Text or RichText
and pass it to the titleText
or messageText
variables.
- Note that
title
will be ignored iftitleText
is notnull
- Note that
message
will be ignored ifmessageText
is notnull
Flushbar(
title: "Hey Ninja", //ignored since titleText != null
message: "Lorem Ipsum is simply dummy text of the printing and typesetting industry", //ignored since messageText != null
titleText: Text("Hello Hero", style: TextStyle(fontWeight: FontWeight.bold, fontSize: 20.0 color: Colors.yellow[600], fontFamily:"ShadowsIntoLightTwo"),),
messageText: Text("You killed that giant monster in the city. Congratulations!", style: TextStyle(fontSize: 16.0, color: Colors.green[fontFamily: "ShadowsIntoLightTwo"),),
)..show(context);
Customize background and shadow #
You can paint the background with any color you want. You can use any shadow you want.
Just give it a backgroundColor
and boxShadows
.
Flushbar(
title: "Hey Ninja",
message: "Lorem Ipsum is simply dummy text of the printing and typesetting industry",
backgroundColor: Colors.red,
boxShadows: [BoxShadow(color: Colors.red[800], offset: Offset(0.0, 2.0), blurRadius: 3.0,)],
)..show(context);
Want a gradient in the background? No problem.
- Note that
backgroundColor
will be ignored whilebackgroundGradient
is notnull
Flushbar(
title: "Hey Ninja",
message: "Lorem Ipsum is simply dummy text of the printing and typesetting industry",
backgroundGradient: LinearGradient(colors: [Colors.blue, Colors.teal]),
backgroundColor: Colors.red,
boxShadows: [BoxShadow(color: Colors.blue[800], offset: Offset(0.0, 2.0), blurRadius: 3.0,)],
)..show(context);
Icon and button action #
Let us put a Icon that has a PulseAnimation
. Icons have this animation by default and cannot be changed as of now.
Also, let us put a button. Have you noticed that show()
returns a Future
?
This Future will yield a value when you call dismiss([T result])
.
I recommend that you specify the result
generic type if you intend to collect an user input.
Flushbar flush;
bool _wasButtonClicked;
@override
Widget build(BuildContext context) {
return Container(
child: Center(
child: MaterialButton(
onPressed: () {
flush = Flushbar<bool>(
title: "Hey Ninja",
message: "Lorem Ipsum is simply dummy text of the printing and typesetting industry",
icon: Icon(
Icons.info_outline,
color: Colors.blue,),
mainButton: FlatButton(
onPressed: () {
flush.dismiss(true); // result = true
},
child: Text(
"ADD",
style: TextStyle(color: Colors.amber),
),
),) // <bool> is the type of the result passed to dismiss() and collected by show().then((result){})
..show(context).then((result) {
setState(() { // setState() is optional here
_wasButtonClicked = result;
});
});
},
),
),
);
}
Flushbar position #
Flushbar can be at FlushbarPosition.BOTTOM
or FlushbarPosition.TOP
.
Flushbar(
flushbarPosition: FlushbarPosition.TOP,
title: "Hey Ninja",
message: "Lorem Ipsum is simply dummy text of the printing and typesetting industry",)..show(context);
Duration and dismiss policy #
By default, Flushbar is infinite. To set a duration, use the duration
property.
By default, Flushbar is dismissible by the user. A right or left drag will dismiss it.
Set isDismissible
to false
to change this behaviour.
Flushbar(
title: "Hey Ninja",
message: "Lorem Ipsum is simply dummy text of the printing and typesetting industry",
duration: Duration(seconds: 3),
isDismissible: false,
)..show(context);
Progress Indicator #
If you are loading something, use a LinearProgressIndicator
If you want an undetermined progress indicator, do not set progressIndicatorController
.
If you want a determined progress indicator, you now have full control over the progress since you own the AnimationController
- There is no need to add a listener to your controller just to call
setState(){}
. Once you pass in your controller,Flushbar
will do this automatically. Just make sure you call_controller.forward()
AnimationController _controller = AnimationController(
vsync: this,
duration: Duration(seconds: 3),
);
Flushbar(
title: "Hey Ninja",
message: "Lorem Ipsum is simply dummy text of the printing and typesetting industry",
showProgressIndicator: true,
progressIndicatorController: _controller,
progressIndicatorBackgroundColor: Colors.grey[800],
)..show(context);
Show and dismiss animation curves #
You can set custom animation curves using forwardAnimationCurve
and reverseAnimationCurve
.
Flushbar(
forwardAnimationCurve: Curves.decelerate,
reverseAnimationCurve: Curves.easeOut,
title: "Hey Ninja",
message: "Lorem Ipsum is simply dummy text of the printing and typesetting industry",
)..show(context);
Listen to status updates #
You can listen to status update using the onStatusChanged
property.
- Note that when you pass a new listener using
onStatusChanged
, it will activate once immediately so you can check in what state the Flushbar is.
Flushbar flushbar = Flushbar(title: "Hey Ninja", message: "Lorem Ipsum is simply dummy text of the printing and typesetting industry");
flushbar
..onStatusChanged = (FlushbarStatus status) {
switch (status) {
case FlushbarStatus.SHOWING:
{
doSomething();
break;
}
case FlushbarStatus.IS_APPEARING:
{
doSomethingElse();
break;
}
case FlushbarStatus.IS_HIDING:
{
doSomethingElse();
break;
}
case FlushbarStatus.DISMISSED:
{
doSomethingElse();
break;
}
}
}
..show(context);
Input text #
Sometimes we just want a simple user input. Use the propertyuserInputForm
.
- Note that buttons, messages, and icons will be ignored if
userInputForm != null
dismiss(result)
will yield result.dismiss()
will yield null.
Flushbar<List<String>> flush;
final GlobalKey<FormState> _formKey = GlobalKey<FormState>();
TextFormField getFormField(String text) {
return TextFormField(
initialValue: text,
style: TextStyle(color: Colors.white),
maxLength: 100,
maxLines: 1,
maxLengthEnforced: true,
decoration: InputDecoration(
fillColor: Colors.white10,
filled: true,
icon: Icon(
Icons.label,
color: Colors.grey[500],
),
border: UnderlineInputBorder(),
helperText: "Helper Text",
helperStyle: TextStyle(color: Colors.grey),
labelText: "Label Text",
labelStyle: TextStyle(color: Colors.grey)),
);
}
flush = Flushbar<List<String>>(
userInputForm = Form(
key: _formKey,
child: Column(
mainAxisSize: MainAxisSize.min,
children: [
getTextFormField("Initial Value"),
getTextFormField("Initial Value Two"),
]
Align(
alignment: Alignment.bottomRight,
child: Padding(
padding: const EdgeInsets.only(top: 8.0),
child: MaterialButton(
textColor: Colors.amberAccent,
child: Text("SUBMIT"),
onPressed: () {
flush.dismiss([_controller1.value.text, _controller2.value.text]);
},
),
),
)
],),),
)..show(context).then((result) {
if (result != null) {
String userInput1 = result[0];
String userInput2 = result[1];
}
});
This example tries to mimic the Material Design style guide
RTL text #
You can add textDirection: Directionality.of(context)
for rtl.
Flushbar(
message: "لوريم إيبسوم هو ببساطة نص شكلي يستخدم في صناعة الطباعة والتنضيد",
icon: Icon(
Icons.info_outline,
size: 28.0,
color: Colors.blue[300],
),
margin: EdgeInsets.all(6.0),
flushbarStyle: FlushbarStyle.FLOATING,
flushbarPosition: FlushbarPosition.TOP,
textDirection: Directionality.of(context),
borderRadius: BorderRadius.circular(12),
duration: Duration(seconds: 3),
leftBarIndicatorColor: Colors.blue[300],
)..show(context);
Flushbar Helper #
I made a helper class to facilitate the creation of the most common Flushbars.
FlushbarHelper.createSuccess({message, title, duration});
FlushbarHelper.createInformation({message, title, duration});
FlushbarHelper.createError({message, title, duration});
FlushbarHelper.createAction({message, title, duration flatButton});
FlushbarHelper.createLoading({message,linearProgressIndicator, title, duration, progressIndicatorController, progressIndicatorBackgroundColor});
FlushbarHelper.createInputFlushbar({textForm});
