animationDuration Duration
Use it to speed up or slow down the animation duration
backgroundColor Color
Will be ignored if backgroundGradient is not null
backgroundGradient Gradient
Makes backgroundColor be ignored.
barBlur double
Default is 0.0. If different than 0.0, blurs only Snack's background. To take effect, make sure your backgroundColor has some opacity. The greater the value, the greater the blur.
borderColor Color
Adds a border to every side of Snack I do not recommend using it with showProgressIndicator or leftBarIndicatorColor.
borderRadius double
Adds a radius to all corners of Snack. Best combined with margin. I do not recommend using it with showProgressIndicator or leftBarIndicatorColor.
borderWidth double
Changes the width of the border if borderColor is specified
boxShadows List<BoxShadow>
boxShadows The shadows generated by Snack. Leave it null if you don't want a shadow. You can use more than one if you feel the need. Check (this example)
dismissDirection SnackDismissDirection
SnackDismissDirection.VERTICAL by default. Can also be SnackDismissDirection.HORIZONTAL in which case both left and right dismiss are allowed.
duration Duration
How long until Snack will hide itself (be dismissed). To make it indefinite, leave it null.
forwardAnimationCurve Curve
The Curve animation used when show() is called. Curves.easeOut is default
hashCode int

@nonVirtual, read-only, inherited
icon Widget
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
isDismissible bool
Determines if the user can swipe or click the overlay (if overlayBlur > 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.
key Key
Controls how one widget replaces another widget in the tree. [...]
final, inherited
leftBarIndicatorColor Color
If not null, shows a left vertical colored bar on notification. It is not possible to use it with a Form and I do not recommend using it with LinearProgressIndicator
mainButton FlatButton
A FlatButton widget if you need an action from the user.
margin EdgeInsets
Adds a custom margin to Snack
maxWidth double
Used to limit Snack width (usually on large screens)
message String
The message displayed to the user.
messageText Widget
Replaces message. Although this accepts a Widget, it is meant to receive Text or RichText
onTap OnTap
A callback that registers the user's click anywhere. An alternative to mainButton
overlayBlur double
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.
overlayColor Color
Default is Colors.transparent. Only takes effect if overlayBlur > 0.0. Make sure you use a color with transparency here e.g. Colors.grey600.withOpacity(0.2).
padding EdgeInsets
Adds a custom padding to Snack The default follows material design guide line
progressIndicatorBackgroundColor Color
A LinearProgressIndicator configuration parameter.
progressIndicatorController AnimationController
An optional AnimationController when you want to control the progress of your LinearProgressIndicator.
progressIndicatorValueColor Animation<Color>
A LinearProgressIndicator configuration parameter.

True if you want to show a LinearProgressIndicator.
snackbarStatus SnackbarStatusCallback
A callback for you to listen to the different Snack status
read / write
snackPosition SnackPosition
Snack can be based on SnackPosition.TOP or on SnackPosition.BOTTOM of your screen. SnackPosition.BOTTOM is the default.
snackStyle SnackStyle
Snack can be floating or be grounded to the edge of the screen. If grounded, I do not recommend using margin or borderRadius. SnackStyle.FLOATING is the default If grounded, I do not recommend using a backgroundColor with transparency or barBlur
title String
The title displayed to the user
titleText Widget
Replaces title. Although this accepts a Widget, it is meant to receive Text or RichText
userInputForm Form
A TextFormField in case you want a simple user input. Every other widget is ignored if this is not null.
