How to use

Import the package in your dart file

import 'package:progress_dialog/progress_dialog_null_safe.dart';

Create and initialise a ProgressDialog object inside the build() method passing context to it

  1. Initialize the ProgressDialog object
    final ProgressDialog pr = ProgressDialog(context);
    
  2. By default it is a normal dialog to show some message, if you would like to use it to show percentage of progress done, specify the optional type parameter and specify if you want your dialog to dismiss when back button is pressed isDismissible parameter (Optional)
    //For normal dialog
    pr = ProgressDialog(context,type: ProgressDialogType.Normal, isDismissible: true/false, showLogs: true/false);
        
    //For showing progress percentage
    pr =  ProgressDialog(context,type: ProgressDialogType.Download, isDismissible: true/false, showLogs: true/false);
    
  3. > Note: Please initialize the ```ProgressDialog```, where you have availability of the context
  4. Style the progress dialog (Optional)
    pr.style(
      message: 'Downloading file...',
      borderRadius: 10.0,
      backgroundColor: Colors.white,
      progressWidget: CircularProgressIndicator(),
      elevation: 10.0,
      insetAnimCurve: Curves.easeInOut,
      progress: 0.0,
      textDirection: TextDirection.rtl,
      maxProgress: 100.0,
      progressTextStyle: TextStyle(
         color: Colors.black, fontSize: 13.0, fontWeight: FontWeight.w400),
      messageTextStyle: TextStyle(
         color: Colors.black, fontSize: 19.0, fontWeight: FontWeight.w600)
      );
    
    Note: You don't need to use all parameters, all of them are optional
    
  5. Showing the progress dialog
    await pr.show();
    
  6. Dynamically update the content shown out there
    pr.update(
      progress: 50.0,
      message: "Please wait...",
      progressWidget: Container(
        padding: EdgeInsets.all(8.0), child: CircularProgressIndicator()),
      maxProgress: 100.0,
      progressTextStyle: TextStyle(
        color: Colors.black, fontSize: 13.0, fontWeight: FontWeight.w400),
      messageTextStyle: TextStyle(
        color: Colors.black, fontSize: 19.0, fontWeight: FontWeight.w600),
      );
    
    Note: You don't need to use all parameters, all of them are optional
    
  7. Dismissing the progress dialog
    pr.hide().then((isHidden) {
      print(isHidden);
    });
    
    // or
    await pr.hide();
    

Navigating to next screens must be done after the completion of Future - hide(). See here for example

Check if progress dialog is showing
bool isProgressDialogShowing = pr.isShowing();
print(isProgressDialogShowing);
Use custom body
    pr = ProgressDialog(
      context,
      type: ProgressDialogType.Normal,
      isDismissible: true,
      /// your body here
      customBody: LinearProgressIndicator(
        valueColor: AlwaysStoppedAnimation<Color>(Colors.blueAccent),
        backgroundColor: Colors.white,
      ),
    );
