The way to use Cordova Plugin "App Rate" in other languages.

something.ts

  rateApp() {
    this.platform.ready().then(() => {
      if (this.platform.is('cordova')) {
        this.appRate.preferences = {
          displayAppName: 'Skills4School',
          simpleMode: true,
          useLanguage: 'en', // Needed. Otherwise will crash.
          storeAppURL: {
            ios: '1350221649',
            android: 'market://details?id=de.skills4school.app'
          },
          customLocale: {
            title: "Bewerte %@",
            message: "Wenn dir %@ gefällt, würdest Du es bitte bewerten? Dies wird nicht länger als eine Minute dauern. Danke für die Unterstützung!",
            cancelButtonLabel: "Nein, danke",
            laterButtonLabel: "Später erinnern",
            rateButtonLabel: "Jetzt bewerten"
          },
          callbacks: {
            onRateDialogShow: function (callback) {
              console.log('rate dialog shown!');
            },
            onButtonClicked: function (buttonIndex) {
              // Use this function to issue Credits for App Ratings
              console.log('Selected index: -> ' + buttonIndex);
            }
          }
        };

        // Opens the rating immediately no matter what preferences you set
        this.appRate.promptForRating(true);
      }
    });
  }
