it fixes the issue Turned out to be fairly straightforward to implement a Loader. Example:
code :
Item {
    id: team1Info

    Loader {
        id: team1ItemLoader
        property string name: model.team1Name
        property string logo: model.team1Logo

        source: (logo) ? "TeamLogoItem.qml" : "TeamItem.qml"
    }
}

will be helpful for those in need The images have to be known during packaging. There's a section about it in the docs.
Put this at the top of the file you define ExpandingCell in:
code :
const MAGNIFYING_GLASS_ICON = require('./CellIcons/MagnifyingGlassIcon.png');
let icon = someCondition ? MAGNIFYING_GLASS_ICON : SOME_OTHER_ICON;
<Image source={icon}/>

this one helps. I figured out a way to do it with valid Html output. You conditionally include an array of elements. Since the only valid child elements of a
tag are
and
, I needed a way to add the fragment without a wrapper.
code :
render() {
    return (
       <dl>
         { 
            this.props.optionalPropObj &&
            [
               <dt key="optionalPropLabel">{this.props.optionalPropObj.label}</dt>,
               <dd key="optionalPropValue">{this.props.optionalPropObj.value}</dd>
            ]
         }

         <dt>Label One</dt>
         <dd>{this.props.foo.one}</dd>

         <dt>Label Two</dt>
         <dd>{this.props.foo.two}</dd>

         <dt>Label Three</dt>
         <dd>{this.props.foo.Three}</dd>

         ...

       </dl>
    );
}
Cannot read property ... from undefined, when conditionally render a component with ref property

Cannot read property ... from undefined, when conditionally render a component with ref property

wish help you to fix your issue I believe the problem is because you are using the same click handler onClickRow to both set showDetailDeposito to true, and then use the ref to call a function. However, because setState is asynchronous, the call to the ref fails as that component has not yet been mounted due to showDetailDeposito being false.
To fix, you could try using the callback in setState to call the ref function once the state has been set.
code :
this.setState({ 
    showDetailDeposito: true
},
() => this.refs.detalle.getDataFromTable(row)
});
