ledger_flutter_plus 1.4.1

A Flutter plugin to scan, connect & sign transactions using your Ledger Nano devices

1.4.1

• Reverted universal_ble to 0.12.0 because 0.13.0 does not seem to connect at all on iOS

1.4.0

• Updated universal_ble package to latest version

1.3.0

• Improved BLE reliability

• Checking device connectivity state during [connect] call to avoid re-attempting BLE connection to already connected device

• Requests are now serialized to prevent issues caused by race conditions (they were very common for unawaited requests)

• Added reusable LedgerSimpleOperation encapsulating the standard structure of ledger requests

• Added LedgerComplexOperation for requests that require multiple (and possibly conditional) chunks of data to be sent as part of a single transaction flow

Breaking Change

• [ConnectionTimeoutException] is now [EstablishConnectionException] which contains a nested exception for the failure reason

NOTE

It is strongly recommended to extend LedgerComplexOperation for transactions requiring multiple chunks of data to be sent because it uses an internal queue to serialize each chunk and make sure:

1. order is maintained
2. no other (differnt) operation will send any data/request to Ledger before current transaction is completed
