Add assets to pubspec — yaml file.

assets:
  -  assets/images/

Step 3: Import

Add this to your gradle.properties file:

org.gradle.jvmargs=-Xmx1536M
android.enableR8=true
android.useAndroidX=true
android.enableJetifier=true

How to implement code in dart file :

You need to implement it in your code respectively:

Create a new dart file called demo_screen.dart inside the lib folder.

Container(
  child: Center(
    child: MaterialButton(
      shape: RoundedRectangleBorder(
          borderRadius: BorderRadius.circular(10.0)),
      color: Colors.cyan,
      padding: EdgeInsets.only(left: 30,right: 30),
      child: Text('Rating Dialog',style: TextStyle
        (color: Colors.white,fontSize: 15),
      ),
      onPressed: _showRatingAppDialog,
    ),
  ),
),

In the body, we will add a container widget. Inside the widget, we will add a center widget, and his child property adds a MaterialButton(). In this button, we will add text, color, button shape, and onPressed method. In this method, we will add a _showRatingAppDialog widget. We will deeply describe it below. When we run the application, we ought to get the screen’s output like the underneath screen capture.

Now, we will deeply define _showRatingAppDialog widget

void _showRatingAppDialog() {
  final _ratingDialog = RatingDialog(
    ratingColor: Colors.amber,
    title: 'Rating Dialog In Flutter',
    message: 'Rating this app and tell others what you think.'
        ' Add more description here if you want.',
    image: Image.asset("assets/images/devs.jpg",
      height: 100,),
    submitButton: 'Submit',
    onCancelled: () => print('cancelled'),
    onSubmitted: (response) {
      print('rating: ${response.rating}, '
          'comment: ${response.comment}');

      if (response.rating < 3.0) {
        print('response.rating: ${response.rating}');
      } else {
        Container();
      }
    },
  );

  showDialog(
    context: context,
    barrierDismissible: true, 
    builder: (context) => _ratingDialog,
  );
}

In the _showRatingAppDialog(), we will add final _ratingDialog is equal to the RatingDialog() plugin. In this dialog, we will add ratingColor mean the rating bar (star icon & glow) color, title, message mean the dialog’s message/description text, image, submitButton mean the submit button’s label/text, onSubmitted mean to returns a RatingDialogResponse with user’s rating and comment values, onCancelled mean call when the user cancels/closes the dialog. Also, we will add showDilaog(). In this dialog, we will add context, barrierDismissible mean set to false if you want to force a rating, and navigated the builder to _ratingDialog. When we run the application, we ought to get the screen’s output like the underneath screen capture.

In this dialog, you will see we will add an image, title, description, star rating, textField for comment, and the last submit button. Also, we will add cancel on the top right corner cross icon.

Code File:

import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';
import 'package:rating_dialog/rating_dialog.dart';

class DemoScreen extends StatefulWidget {
  @override
  _DemoScreenState createState() => _DemoScreenState();
}

class _DemoScreenState extends State<DemoScreen> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      backgroundColor: Colors.teal[50],
      appBar: AppBar(
        backgroundColor: Colors.black,
          title: Text('Rating Dialog In Flutter'),
        automaticallyImplyLeading: false,
      ),
      body: Container(
        child: Center(
          child: MaterialButton(
            shape: RoundedRectangleBorder(
                borderRadius: BorderRadius.circular(10.0)),
            color: Colors.cyan,
            padding: EdgeInsets.only(left: 30,right: 30),
            child: Text('Rating Dialog',style: TextStyle
              (color: Colors.white,fontSize: 15),
            ),
            onPressed: _showRatingAppDialog,
          ),
        ),
      ),
    );

  }

  void _showRatingAppDialog() {
    final _ratingDialog = RatingDialog(
      ratingColor: Colors.amber,
      title: 'Rating Dialog In Flutter',
      message: 'Rating this app and tell others what you think.'
          ' Add more description here if you want.',
      image: Image.asset("assets/images/devs.jpg",
        height: 100,),
      submitButton: 'Submit',
      onCancelled: () => print('cancelled'),
      onSubmitted: (response) {
        print('rating: ${response.rating}, '
            'comment: ${response.comment}');

        if (response.rating < 3.0) {
          print('response.rating: ${response.rating}');
        } else {
          Container();
        }
      },
    );

    showDialog(
      context: context,
      barrierDismissible: true, 
      builder: (context) => _ratingDialog,
    );
  }

}
