Step By Step

1st Flutter Part

here you assign a value

Future<SharedPreferences> _prefs = SharedPreferences.getInstance();

final SharedPreferences prefs = await _prefs;
  await prefs.setString("SharedPrefKey", definition)

then you can use it in flutter where ever you want

String stringFromShared;

Future<SharedPreferences> _prefs = SharedPreferences.getInstance();

stringFromShared = prefs.getString("SharedPrefKey");

2nd Android Part

private SharedPreferences sharedPreferences;


sharedPreferences = getSharedPreferences("FlutterSharedPreferences", Context.MODE_PRIVATE);
    sharedPreferences.getString("flutter." + "SharedPrefKey", "");

the key point here is usage of prefix "flutter."

For the noobs out here,

import android.content.SharedPreferences
...
var PRIVATE_MODE = 0
val mPrefs = getSharedPreferences("FlutterSharedPreferences", PRIVATE_MODE)
mPrefs.getString("flutter." + "key", "")

Add this to your code. It will work.

SharedPreferences mPrefs = context.getSharedPreferences("FlutterSharedPreferences", context.MODE_PRIVATE);
String value = mPrefs.getString("flutter." + "YourSharedpreferencekey", "");

Dart sharedPreference use native java code which means they are using the same sharedPreferences, you can access that sharedPreferences key in Android by calling sharedPreferences from native code (Java or Kotlin).
