Accordion List within ionic 2 - ionic-framework

Question

I've create a custom components named Accordion within iconic 2 and working in browser perfectly but on device not working.
I've split my code up into components, where
Home.ts
import { Component } from '#angular/core';
import { NavController } from 'ionic-angular';
import {DataCards} from '../../components/data-cards/data-cards';
import {Data} from '../../components/data/data';
#Component({
selector: 'page-home',
templateUrl: 'home.html'
})
export class HomePage {
public dataList: Data[];
constructor(public navCtrl: NavController) {
this.dataList = [
new Data('title 1', 'Lorem Ipsum is simply dummy text of the printing and typesetting industry. ','ios-remove-circle-outline', true),
new Data('title 2', 'Lorem Ipsum is simply dummy text of the printing and typesetting industry. ','ios-add-circle-outline', false),
new Data('title 3', 'Lorem Ipsum is simply dummy text of the printing and typesetting industry. ','ios-add-circle-outline', false)
];
}
}
and the corresponding HTML
<ion-content padding>
<data-cards [data]="dataList"></data-cards>
</ion-content>
contain my custom component data-cards. data-cards has an input parameter data, through which the list of data is passed.
data.ts
import { Component } from '#angular/core';
#Component({
selector: 'data',
templateUrl: 'data.html'
})
export class Data {
constructor(public title: string, public details: string, public icon: string, public showDetails: boolean) {}
}
data-cards.ts
import { Component } from '#angular/core';
import { Data } from '../data/data';
#Component({
selector: 'data-cards',
inputs: ['data'],
templateUrl: 'data-cards.html'
})
export class DataCards {
public data: Data[];
constructor() {}
toggleDetails(data: Data) {
if (data.showDetails) {
data.showDetails = false;
data.icon = 'ios-add-circle-outline';
} else {
data.showDetails = true;
data.icon = 'ios-remove-circle-outline';
}
}
}
app.module.ts
import { NgModule } from '#angular/core';
import { IonicApp, IonicModule } from 'ionic-angular';
import { MyApp } from './app.component';
import { HomePage } from '../pages/home/home';
import { Data } from '../components/data/data';
import { DataCards } from '../components/data-cards/data-cards';
#NgModule({
declarations: [
MyApp,
HomePage,
Data,
DataCards
],
imports: [
IonicModule.forRoot(MyApp)
],
bootstrap: [IonicApp],
entryComponents: [
MyApp,
HomePage,
Data,
DataCards
],
providers: []
})
export class AppModule {}
When run on iOS ( ionic run ios ) i've got an error like below :
[08:44:54] Error: Error at /Users/imac/Documents/ionic2Accordion/.tmp/components/data/data.ngfactory.ts:29:71

so my question : how i can resolve this problem any suggestion ?

Answer 1

In data-card.ts change
public data: Data[];
o be
Input() data: Data[];
since you will be assigning it from the component creation in the home.html? You'll also need to import the Input module via
import { Component, Input } from '#angular/core';
