How do I use image URI for local images instead of source ?

[akhan118]

Hi all,

I'm using react native camera and the takePicture function returns a promise.

the promise has the usual data of an image object , {uri://file}

I would like to take that 'uri' and set it as state so I can pass it to react-native- viewer .

The problem is that I can't set it .

because the require() function gives an error.

example

    props: {
        // Or you can set source directory.
        source: require(data.uri)
    }

it gives an error because the image has to be available when compile. and data.uri is not available when compile.

Here is a full example of the promise and image

  takePicture = async function() {
    if (this.camera) {
      const data = await this.camera.takePictureAsync()
      .then((data) => {
        this.setState(prevState => {
          return {
            ...prevState,
            Image:[
              ...prevState.Image,
              {
                url: '',
                  props: {
             /// it seems that I can't do that and it causes and error
             ///  how can I pass a local image to the viewer without using require() ?
                      source: require(data.uri),  

                  },
              },
             ]
          };
        })

});
    }
  };

causes this error

                  this.setModalVisible(!this.state.modalVisible);
                }}
                enableSwipeDown={true}
              />

How can I pass a local image that I captured from camera to the viewer ?

Thanks in advance.

I ended up putting the viewer in a component of it's own and pass the images as a state. it worked for me with no issues.

Hi,

Image data has uri key not url You have to add url key in your image data.

Update your image data as bellow.

var url = { url: data.uri }
var newImageData = { ...data, ...url }

<ImageViewer imageUrls={[ { url: '', props: { source: { uri: data.uri, }, }, }, ]} />
