can't find variable function declaration react native

I get the error "variable uploadImageAsync cannot be found"

uploadImageAsync = async (uri) => {
  console.log("In upload image asnyc!");
}

And this is where I call it from.

_handleImagePicked = async pickerResult => {
let uploadResponse, uploadResult;

  this.setState({ uploading: true });

  if (!pickerResult.cancelled) {
    uploadResponse = await uploadImageAsync(pickerResult.uri);
    uploadResult = await uploadResponse.json();
    this.setState({ image: uploadResult.location });
  }
    this.setState({ uploading: false });
};

How can I get around this?

So far I've tried:

async function uploadImageAsync(uri) {

I've also tried:

async uploadImageAsync(uri) {

If the uploadImageAsync function defined in the same component, you need call this.uploadImageAsync.

Otherwise, you must import it from the other module

or define the function outside the component in the same file.
