在flutter中使用rate_my_app包？

Question

谁能告诉我，你是如何在 Flutter 应用中使用 rate_my_app https://pub.dev/packages/rate_my_app 包来增加用户评论的？

一个示例代码会很有用吗？

Answer 1

rate_my_app 只是一个提醒用户评价您的应用的插件。如果您的应用满足用户的需求，它将增加用户的正面评价。

Skyost的示例代码：

import 'package:flutter/material.dart';
import 'package:rate_my_app/rate_my_app.dart';

/// Main rate my app instance.
RateMyApp _rateMyApp = RateMyApp();

/// First plugin test method.
void main() {
  _rateMyApp.init().then((_) {
    runApp(_RateMyAppTestApp());
    print('Minimum days : ' + _rateMyApp.minDays.toString());
    print('Minimum launches : ' + _rateMyApp.minLaunches.toString());

    print('Base launch : ' + _dateToString(_rateMyApp.baseLaunchDate));
    print('Launches : ' + _rateMyApp.launches.toString());
    print('Do not open again ? ' + (_rateMyApp.doNotOpenAgain ? 'Yes' : 'No'));

    print('Are conditions met ? ' + (_rateMyApp.shouldOpenDialog ? 'Yes' : 'No'));
  });
}

/// Returns a formatted date string.
String _dateToString(DateTime date) => date.day.toString().padLeft(2, '0') + '/' + date.month.toString().padLeft(2, '0') + '/' + date.year.toString();

/// The main rate my app test widget.

请按照以下代码。

Answer 3

这里是从 main 调用的屏幕中使用 rate_my_app 的示例

import 'package:flutter/material.dart';
import 'package:rate_my_app/rate_my_app.dart';

/// Main Rate my app instance.
RateMyApp _rateMyApp = RateMyApp(
  preferencesPrefix: 'rateMyApp_',
  minDays: 7,
  minLaunches: 10,
  remindDays: 7,
  remindLaunches: 10,
  // appStoreIdentifier: '',
  // googlePlayIdentifier: '',
);

class HomeScreen extends StatefulWidget {
  @override
  _HomeScreenState createState() => _HomeScreenState();
}

class _HomeScreenState extends State<HomeScreen> {
  @override
  void initState() {
    super.initState();
    _rateMyApp.init().then((_) {
      _rateMyApp.conditions.forEach((condition) {
        if (condition is DebuggableCondition) {
          print(condition.valuesAsString());
          // We iterate through our list of conditions and we print all debuggable ones.
        }
      });

      print('Are all conditions met ? ' +
          (_rateMyApp.shouldOpenDialog ? 'Yes' : 'No'));

      if (_rateMyApp.shouldOpenDialog) _buildShowStarRateDialog(context);
    });
  }

    _buildShowStarRateDialog(BuildContext context) {
    _rateMyApp.showStarRateDialog(context, actionsBuilder: (_, count) {
      final Widget cancelButton = RateMyAppNoButton(
        // We create a custom "Cancel" button using the RateMyAppNoButton class.
        _rateMyApp,
        text: 'CANCEL',
        callback: () => setState(() {}),
      );
      if (count == null || count == 0) {
        // If there is no rating (or a 0 star rating), we only have to return our cancel button.
        return [cancelButton];
      }

      // Otherwise we can do some little more things...
      String message = 'You\'ve put ' + count.round().toString() + ' star(s). ';
      Color color;
      switch (count.round()) {
        case 1:
          message += 'Did this app hurt you physically ?';
          color = Colors.red;
          break;
        case 2:
          message += 'That\'s not really cool man.';
          color = Colors.orange;
          break;
        case 3:
          message += 'Well, it\'s average.';
          color = Colors.yellow;
          break;
        case 4:
          message += 'This is cool, like this app.';
          color = Colors.lime;
          break;
        case 5:
          message += 'Great ! <3';
          color = Colors.green;
          break;
      }

      return [
        FlatButton(
          child: const Text('OK'),
          onPressed: () async {
            print(message);
            Toast.show(message, context,
                duration: Toast.LENGTH_LONG, gravity: Toast.TOP);

            // This allow to mimic a click on the default "Rate" button and thus update the conditions based on it ("Do not open again" condition for example) :
            await _rateMyApp.callEvent(RateMyAppEventType.rateButtonPressed);
            Navigator.pop<RateMyAppDialogButton>(
                context, RateMyAppDialogButton.rate);

            setState(() {});
          },
        ),
        cancelButton,
      ];
    });

}
