Breaking Changes

Flutter: Linting & clean up (#1202)

How to Migrate:
- Update all imports of import 'package:amplify_flutter/amplify.dart'; to import 'package:amplify_flutter/amplify_flutter.dart';
API: This version changes GraphQL subscription interface to use Streams. See the amplify_api page for additional information.
Auth: The fetchAuthSession API will throw a SignedOutException when the user has not signed in, and a SessionExpiredException when the tokens have expired.
Auth: The getCurrentUser API will return an AuthUser if the user is still authenticated but the session has expired.
DataStore: ModelProvider and ModelField interface changes

How to Migrate:
- Install the required version of @aws-amplify/cli as described on the amplify_datastore page
- Run amplify codegen models to regenerate models
DataStore: This version introduces a breaking change to Android Apps as an existing bug writes Double and Boolean values as TEXT in local SQLite database. The fix corrects this behavior. Hence, directly applying this fix may raise SQL error while reading from and writing to local database.

How to Migrate:

Invoke Amplify.DataStore.clear() on App start after upgrading to the latest version of Amplify Flutter. This API clears and recreates local database table with correct schema.

NOTE: Data stored in local database and not synced to cloud will be lost, as local migration is not supported.
