rate_my_app只是一个提醒用户评价您的应用程序的插件。如果您的应用满足用户的需求，它将增加正面用户的评论。
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'));
});
}

这里是从主屏幕调用的在屏幕上使用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(

}
});

(_rateMyApp.shouldOpenDialog ? 'Yes' : 'No'));

);
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:

}
return [
