title: React-Native: save user preferences
body: <p>Native developers,</p>
  
  <p>I really searched a lot but couldn't find anything that fits my needs. </p>
  
  <p>I am new to react native and have a question. 
  I wonder how I can save user preferences of my app.</p>
  
  <p>For example, I am displaying a dismissible badge on my screen -> user dismisses it -> how do I save this decision so the badge won't appear on every start again?</p>
  
  <p>I thought about writing a .json file where all preferences are defined and read it on every start. </p>
  
  <p>Is this a common way to realize it or is there any other solution. </p>
  
  <p>Thank you very much</p>
