Image doesn't render local source (path with no extension name)

🐛 Bug Report

// write image to local path(iOS native code)
  NSString *path = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES).firstObject;
  NSString *filePath = [path stringByAppendingPathComponent:[NSString stringWithFormat:@"image"]];
  [UIImagePNGRepresentation(image) writeToFile:filePath atomically:YES]

// under iOS (it works great)
[UIImage imageWithContentsOfFile: filePath];

// under react native (Could not find image filePath)
<Image source={{ uri:  filePath }} />

// If the filePath with extension name it works on both
  NSString *filePath = [path stringByAppendingPathComponent:[NSString stringWithFormat:@"image.png"]];
  [UIImagePNGRepresentation(image) writeToFile:filePath atomically:YES]

Reason

Reason is the file has no extension name when write to path! It doesn’t master under iOS, not work under React native!

Why I need to render image from local source

My project is using a iOS native IM framework. The framework save image to the local path without extension. Now I build chat ui by react native, so I must be able to render the image!
