How to create Toast in Flutter

Question

Can I create something similar to Toasts in Flutter  Just a tiny notification window that is not directly in the face of the user and does not lock or fade the view behind it

For the ones that are looking for a Toast what can survive the route changes the SnackBar might not be the best option   Have a look at Overlay instead   https   api flutter dev flutter widgets Overlay-class html

SnackBar is definitely the right class to use  as pointed out by Darky     One tricky thing about showSnackBar is getting to the ScaffoldState  if you re trying to call showSnackBar within the build method where you construct your Scaffold    You might see an error like this  which includes some text explaining how to solve the problem   --   EXCEPTION CAUGHT BY GESTURE   ------------------------------------------------------------------- The following assertion was thrown while handling a gesture  Scaffold of   called with a context that does not contain a Scaffold  No Scaffold ancestor could be found starting from the context that was passed to Scaffold of    This usually happens when the context provided is from the same StatefulWidget as that whose build function actually creates the Scaffold widget being sought  There are several ways to avoid this problem  The simplest is to use a Builder to get a context that is  under  the Scaffold  For an example of this  please see the documentation for Scaffold of      https   docs flutter io flutter material Scaffold of html A more efficient solution is to split your build function into several widgets  This introduces a new context from which you can obtain the Scaffold  In this solution  you would have an outer widget that creates the Scaffold populated by instances of your new inner widgets  and then in these inner widgets you would use Scaffold of    A less elegant but more expedient solution is assign a GlobalKey to the Scaffold  then use the key currentState property to obtain the ScaffoldState rather than using the Scaffold of   function  The context used was    MyHomePage When the exception was thrown  this was the stack   0      Scaffold of  package flutter src material

 ready  ----------------------------------------------------------------------------------------------------   You can either pass a GlobalKey to your Scaffold constructor   class MyHomePage extends StatelessWidget      override   Widget build BuildContext context        final key   new GlobalKey lt ScaffoldState gt         return new Scaffold        key  key        floatingActionButton  new Builder          builder   BuildContext context              return new FloatingActionButton              onPressed                     key currentState showSnackBar new SnackBar                  content  new Text  Sending Message                                                 tooltip   Increment               child  new Icon Icons add                                                  Or you can use a Builder to create a BuildContext that is a child of the Scaffold   class MyHomePage extends StatelessWidget      override   Widget build BuildContext context        return new Scaffold        floatingActionButton  new Builder          builder   BuildContext context              return new FloatingActionButton              onPressed                     Scaffold of context  showSnackBar new SnackBar                  content  new Text  Sending Message                                                 tooltip   Increment               child  new Icon Icons add                                                  Finally  you could split your widget into multiple classes  which is the best long-term approach

There is a three-way to show toast on flutter App  I will tell you about all three way that I know and choose which one you want to use  I would recommend the second one  1  using of the external package  this is the first method which is the easiest way to show toast on flutter app  first of all  you have to add this package to pubspec YAML flutter just toast  version here  then import the package in the file where you want to show a toast   package flutter just toast flutter just toast dart    and the last step shows the toast  Toast show  message   quot Your toast message quot               duration  Delay SHORT              textColor  Colors black    2   using official way  this method is also simple but you have to deal with it  I am not saying that it is hard it is simple and clean I would recommend this method  for this method  all you have to do show toast is using the below code  Scaffold of context  showSnackBar SnackBar            content  Text  quot Sending Message quot                 but remember that you have to use the scaffold context  3  using native API  now  this method does not make sense anymore when you already have the two methods above  using this method you have to write native code for android and iOS and then convert it to plugin and you are ready to go  this method will consume your time and you have to reinvent the wheel  which has already been invented

In case the Fluttertoast package given so far doesnt work    Then I will suggest you try toast  It has no frills and no ceremony   It just works  I noticed a bug within the example given within its Readme though   Toast show  Toast plugin app   duration  Toast LENGTH SHORT  gravity   Toast BOTTOM   While the method requires a context  So do well to add  context  like this  Toast show  Toast plugin app   context  duration  Toast LENGTH SHORT  gravity   Toast BOTTOM   There is a chance that this would have been fixed by the time you checked though  I already submitted a PR

The answer Scaffold of context  showSnackBar      has not worked in most cases  I suggest the optimal method be declaring a scaffoldState key within the class and assigning it to Scaffold like below GlobalKey lt ScaffoldState gt   scaffoldKey   new GlobalKey lt ScaffoldState gt      and then Scaffold    key   scaffoldKey           when you want to show the Snackbar do this    scaffoldKey currentState showSnackBar SnackBar    content  Text  quot This works  quot
