I’m trying to pass my javascript code (Reactjs) the path image:

And in the code I write like this:

source={{ uri: this.state.modelo.baner[0].url_img }}

And the browser accuses this error:

Typeerror: Cannot read Property '0' of Undefined

1

Probably that this.state.modelo has not yet got the baner defenido... how does this this.state.modelo is being filled in/updated?

The image above is a part of the.log console of this This.

What gives console.log(JSON.stringify(this.state.modelo));?

The best way I know to verify the existence of "props" and "States" after rendered, is with the extension React Developer Tools.
