title: react-native-maps LocalTile storage of tiles
body: <p>With the new <code>LocalTile</code> feature of react-native-maps 0.19+, you can store tile images locally instead of using Apple or Google maps.</p>
  
  <p>However, I haven't yet solved (because I can't find it in the docs and the source isn't giving me the clues I need) how to properly store and then address the local tiles. </p>
  
  <p>I have my tiles generated and in the proper folder structure, and was hoping to place it alongside my other source files in, for example, <code>./data/tiles/{z}/{x}/{y}.png</code>. But when using that or variations of that for my <code>pathTemplate</code> prop I just get the blank map. I'm assuming this is because MetroBundler or something else isn't trying to load up the <code>data/tiles</code> folder because I never <code>require</code> it as I would other resources.</p>
  
  <p>Do I have to include the assets in the actual <code>ios</code> or <code>android</code> folders as a bundled asset of some sort? Or is there a way to include all the static resources in the project somehow to get them pulled over? Or am I just misunderstanding the <code>pathTemplate</code> property and file storage in general? Thanks!</p>
