new questiontype star-rating

[tim-lutz]

There was no star-rating feature. So I modified a copy of the choose image feature I tested for android (I did not test the key instead of url feature).

It is used like the choice image feature, for every choice there is an image for an active and not-active star. A function tests, which image should be displayed according to the selected item.

Because it is a derivate of choose image feature (no visual changes, but to display active or not-active picture) it should work on other devices as good as on android. You can use the starActive and starNotActive images in example to test it and for the offical example assets. These files are CC0 created by me with inkscape. What has to be done to get multilang-support: add new string to other "lang" json-files

To test the new questiontype, just copy this to the LinearSurveyPage example: final imagesstars = [
RPStarChoice(
starActiveUrl: 'assets/images/starActive.png',
starNotActiveUrl:'assets/images/starNotActive.png' ,
value: -2,
description: '1 star',
),
RPStarChoice(
starActiveUrl: 'assets/images/starActive.png',
starNotActiveUrl: 'assets/images/starNotActive.png',
value: -1,
description: '2 stars',
),
RPStarChoice(
starActiveUrl: 'assets/images/starActive.png',
starNotActiveUrl: 'assets/images/starNotActive.png',
value: 0,
description: '3 stars',
),
RPStarChoice(
starActiveUrl: 'assets/images/starActive.png',
starNotActiveUrl: 'assets/images/starNotActive.png',
value: 1,
description: '4 stars',
),
RPStarChoice(
starActiveUrl: 'assets/images/starActive.png',
starNotActiveUrl: 'assets/images/starNotActive.png',
value: 2,
description: '5 stars',
),
];

final imageChoiceAnswerStars = RPStarChoiceAnswerFormat(choices: imagesstars);

To view the example in LinearSurveyPage add "imageChoiceQuestionStepStars" to the steps section

To view the example add to LinearSurveyPage
final imageChoiceQuestionStepStars = RPQuestionStep(
identifier: "imageStepIDStars",
title: "Rate your experience.",
answerFormat: imageChoiceAnswerStars,
);

if that helps: the image files can also be shared with MIT license, if you used to do that.
