Storage sometimes returns random data

[Sorunome]

Using android, Xperia 10 w/ LOS 10

Sometimes the storage returns random junk data instead of the actual data stored by the key. Interestingly this random data is the same every single time.

Some other times a platform exception is thrown:

The following code seems to be able to fetch a value from the store significantly more reliably:

    try {
      final val1 = await secureStorage.read(key: key);
      final val2 = await secureStorage.read(key: key);
      if (val1 == val2) {
        return val1;
      }
      // else read a third time
      return await secureStorage.read(key: key);
    } catch (e, s) {
      try {
        final val1 = await secureStorage.read(key: key);
        final val2 = await secureStorage.read(key: key);
        if (val1 == val2) {
          return val1;
        }
        // else read a third time
        return await secureStorage.read(key: key);
      } catch (_) {
        return null;
      }
    }

Perhaps the library should adapt better re-trying on errors or thelike?

It might be important to point out that these reads happen very early in the apps startup cycle

@Sorunome refer to #161 for a likely work around

Ah, thank you. Closing this issue as a duplicate of that one.
