ContentValues class

This class is used to store a set of values that the content provider/resolver can process https://developer.android.com/reference/android/content/ContentValues

This class allows storing Java types that are not presented in Dart:

  • Byte
  • Short
  • Integer
  • Float

They are still represented by corresponding Dart types int and double, and when put into ContentValues, keep being stored as is, without overflowing.

For example, if 500 is passed into putByte, it will remain 500 on getByte.

But, when sent over native channels, these values are converted to actual Java types, and therefore an overflow will happen.
