React-native failed propType on Image component

I am just starting out with React-native and have a pretty decent grasp on React for creating web apps... I am running into a confusing issue here that never occured when working with react for the web.

Basically I am rendering a component whose image is being dynamically generated by mapping over an array of objects in its parent component.

export default class ImageComponent extends React.Component {
  render() {
    return (
        <Image source={this.props.source}/>
    );
  }
};

And its parent component:

export default class MainComponent extends React.Component {
  constructor(props) {
    super(props);
   this.state = {
      images:[
        { src: './src/images/1.png'},
        { src: '/src/images/2.png'},
        { src: './src/images/3.png'}
      ]
    }
   }

  render() {
    let images = this.state.images.map((image) => {
      return(<ImageComponent source={image.src}  />);
    })

    return (
      <View>
        {images}
      </View>
    );
  }
};

In device simulator I am getting the following error:

"Warning: Failed propType:Invalid prop 'source' supplied to 'Image' check the render method of 'BasicComponent'"

Does anyone know what could be going on here?

<Image source={require('./pathToImage/image.png')}/>

This also works if your using something in your project files rather than a URL.

<Image source= {{uri: "https://miro.medium.com/v2/resize:fit:1024/1*QY5S4senfFh-mIViSi5A_Q.png"}} style = {{width:100,height:100}}/>

add uri name in source, it will work.

you should be use uri for set source image 

return (
  <Image 
    source={{uri: 'https://reactnative.dev/docs/assets/p_cat2.png'}}
  />
);

You should either require the local assets or use object with uri key.

So either in MainComponent:

this.state = {
  images:[
    require('./src/images/1.png'),
    require('./src/images/2.png'),
    require('./src/images/3.png')
  ]
}

or in BasicComponent:

return (
  <Image 
    source={{uri: this.props.source}}
  />
);
