DriftIsolate.fromConnectPort constructor

DriftIsolate.fromConnectPort(
  1. SendPort connectPort, {
  2. bool serialize = true,
})

Creates a DriftIsolate talking to another isolate by using the connectPort.

Internally, drift uses ports from dart:isolate to send commands to an internal server dispatching database actions. In most setups, those ports can send and receive almost any Dart object. In special cases though, the platform only supports sending simple types across send types. In particular, isolates across different Flutter engines (such as the ones spawned by the workmanager package) are unable to handle most objects. To support those setups, drift can serialize its internal communication channel to only send simple types across isolates. The serialize parameter, which is enabled by default, controls this behavior.

In most scenarios, serialize can be disabled for a considerable performance improvement.

Implementation

DriftIsolate.fromConnectPort(this.connectPort, {this.serialize = true});
