Anyway, not only helps you display a dialog with a blurred background, NDialog is here to help you do a lot of things. for example, with NDialog you can display ProgressDialog to the user once until it meets the end of Future!

First of all, let's leave the old style with showDialog(...), with NDialog I provide dialog extensions, you can simply call .show(context) at the end of all of your dialog and let the magic work!

There are 2 types of dialogs, they are Dialog (popup dialog) and ProgressDialog

Dialog

In Dialog, there are 3 types, they are NDialog, NAlertDialog, ZoomDialog.

NDialog

Is a raw dialog where you can view them right away without anything else

  NDialog(
    dialogStyle: DialogStyle(titleDivider: true),
    title: Text("NDialog"),
    content: Text("This is NDialog's content"),
    actions: <Widget>[
      TextButton(child: Text("Okay"), onPressed: () => Navigator.pop(context)),
      TextButton(child: Text("Close"), onPressed: () => Navigator.pop(context)),
    ],
  ).show(context);

NAlertDialog

Is a dialog where you can directly set the background attributes without be wrapped by DialogBackground and you can simply display them.

  NAlertDialog(
    dialogStyle: DialogStyle(titleDivider: true),
    title: Text("NAlertDialog"),
    content: Text("This is NAlertDialog's content"),
    actions: <Widget>[
      TextButton(child: Text("Okay"), onPressed: () => Navigator.pop(context)),
      TextButton(child: Text("Close"), onPressed: () => Navigator.pop(context)),
    ],
  ).show(context);

ZoomDialog

Is a dialog that you can zoom on it, you can zoom all type of widget on this dialog, simplye write this code and boom, there you go!

  ZoomDialog(
    zoomScale: 5,
    child: Container(
      child: Text("Zoom me!"),
      color: Colors.white,
      padding: EdgeInsets.all(20),
    ),
  ).show(context);

Progress Dialog

In ProgressDialog, there are 2 types, they are ProgressDialog and CustomProgressDialog.

ProgressDialog

Will display the ProgressDialog with Android native style.

  ProgressDialog progressDialog = ProgressDialog(
    context,
    blur: 10,
    title: Text("Title of ProgressDialog"),
    message: Text("Content of ProgressDialog"),
    onDismiss: () => print("Do something onDismiss"),
  );
  progressDialog.show();

  //Set loading with red circular progress indicator and change the title and message
  await Future.delayed(Duration(seconds: 5));
  progressDialog.setLoadingWidget(CircularProgressIndicator(valueColor: AlwaysStoppedAnimation(Colors.red)));
  progressDialog.setTitle(Text("ProgressDialog Title changed"));
  progressDialog.setMessage(Text("It will change again after 5 seconds"));

  //Show dialog
  progressDialog.show();

  //After 5 seconds, change the title, message and loading widget to null (default widget is CircularProgressIndicator)
  await Future.delayed(Duration(seconds: 5));
  progressDialog.setLoadingWidget(null);
  progressDialog.setMessage(Text("ProgressDialog will dismiss after 5 seconds"));
  progressDialog.setTitle(Text("Last changes"));

  //After 5 seconds, dismiss the dialog
  await Future.delayed(Duration(seconds: 5));
  progressDialog.dismiss();

CustomProgressDialog

Will display a progress dialog with customizable widgets

  CustomProgressDialog progressDialog = CustomProgressDialog(
    context,
    blur: 10,
    onDismiss: () => print("Do something onDismiss"),
  );
  //Set loading with red circular progress indicator
  progressDialog.setLoadingWidget(CircularProgressIndicator(valueColor: AlwaysStoppedAnimation(Colors.red)));

  //Show dialog
  progressDialog.show();

  //After 5 seconds, change the loading widget to null (default widget is CircularProgressIndicator)
  await Future.delayed(Duration(seconds: 5));
  progressDialog.setLoadingWidget(null);

  //After 5 seconds, dismiss the dialog
  await Future.delayed(Duration(seconds: 5));
  progressDialog.dismiss();

Show Progress Dialog Once with .future()

This is what I'm talking about, Each Progress Dialog has a .future(context) static function, which will help you display the progress dialog once until Future is completed!

  ///ProgressDialog
  ProgressDialog.future(
    context,
    title: Text("ProgressDialog.future()"),
    message: Text("This will finis after 5 seconds"),
    future: Future.delayed(Duration(seconds: 5), () => "The end of future (5 seconds)"),
    onProgressError: (error) => print("Do something onProgressError"),
    onProgressFinish: (data) => print("Do something onProgressFinish"),
    onDismiss: () => print("Dismissed"),
  ).then((value) => print(value));

  ///CustomProgressDialog
  CustomProgressDialog.future(
    context,
    future: Future.delayed(Duration(seconds: 5), () => "The end of future (5 seconds)"),
    onProgressError: (error) => print("Do something onProgressError"),
    onProgressFinish: (data) => print("Do something onProgressFinish"),
    onDismiss: () => print("Dismissed"),
  ).then((value) => print(value));

Future Extensions

Now you can show a dialog on every futures by simply add a single code.

  //Make sure you import ndialog to call extensions function
  import 'package:ndialog/ndialog.dart';

  ...
  Future.delayed(Duration(seconds: 3)).showProgressDialog(
    context,
    title: Text("Title of ProgressDialog"),
    message: Text("This dialog will be close after 3 seconds"),
  );
  //or
  Future.delayed(Duration(seconds:3)).showCustomProgressDialog(context);

Dialog Extensions!

You can simply call show(context) at the end of Flutter's built-in dialogs.

  //Make sure you import ndialog to call extensions function
  import 'package:ndialog/ndialog.dart';

  ...

  AlertDialog( ... ).show(context);
  SimpleDialog( ... ).show(context);
  Dialog( ... ).show(context);
  CupertinoAlertDialog( ... ).show(context);

DialogBackground

You can use DialogBackground to create your own custom dialog and display them easily, you can also change the barrierColor / background color and add little bit blur effects there.

Note : BlurDialogBackground is depreceted, use DialogBackground instead!

  DialogBackground(
    blur: 5,
    dialog: AlertDialog(
      title: Text("NAlert Dialog"),
      content: Text("NAlertDialog with Blur background"),
      actions: <Widget>[
        TextButton(child: Text("Okay"), onPressed: () => Navigator.pop(context)),
        TextButton(child: Text("Close"), onPressed: () => Navigator.pop(context)),
      ],
    ),
  ).show(context);

Dialog Transition

Now you can show Dialog(Flutter native dialog included) with animated transition, by simply write

yourDialog.show(context, transitionType: DialogTransitionType.Bubble);

Choose your customized transition and show them right away!
