Oh I see the issue now, if you give this a default value of undefined the solution will work because below you are checking:

this.props.listContainerStyles ? this.props.listContainerStyles : [styles.flex1]

and empty array will be truthy value

I think this can be rewritten as

Suggested change
<View style={[...(this.props.listContainerStyles ? this.props.listContainerStyles : [styles.flex1])]}>
<View style={[...(this.props.listContainerStyles || [styles.flex1])]}>

Though I'm a little unsure about the use of spread syntax here. Wouldn't [...(x)] be equal to just x?

I think this can be further simplified to:

Suggested change
<View style={[...(this.props.listContainerStyles ? this.props.listContainerStyles : [styles.flex1])]}>
<View style={this.props.listContainerStyles || [styles.flex1]}>

Is there a specific reason you'd want to have the syntax in my comment above instead?

yeah if we want to make this super clean we can just do this

const defaultProps = {
    listContainerStyles: [styles.flex1],
};

...
<View style={this.props.listContainerStyles}

@marcaaron I love this clean solution! Will implement it and push it. Thank you!
