custom key for renderItem about react-native-image-viewing HOT 3 CLOSED

Having the same issuse

from react-native-image-viewing.

Line 56 of the ImageViewing.js keyExtractor={(imageSrc) => imageSrc.uri || `${imageSrc}`} is the culprit.
You can get around this by setting it to something else I use a property on my object called name which is a unique filename using a timestamp.

This mainly happens when the url/uri is the same or it is the same file. This causes major inefficiency if using uri of base64 since the keys are compared to each other leading to slower load times. A remedy for this would to allow developers to use custom keyextractors or use a uuid generator.

@CarlOmega Submitted a PR #105 implementing custom keyExtractor. I hope this will solve this issue. Would like to hear from maintainers.
