bridra_flutter 0.2.0

Reusable Flutter RPC and Go sidecar runtime for Bridra applications.

bridra_flutter

Reusable Flutter transport package for Bridra 0.1 applications.

This package is licensed under the MIT License, Copyright (c) 2026 Cluion. It is the Flutter-facing runtime package for the Bridra framework.

It provides:

• the common RPC client contract and error types;
• an HTTP RPC client for mobile, Web, and remote backends;
• a managed Go sidecar client for Windows, macOS, and Linux;
• a conditional default connector that selects the platform transport.

Desktop executable discovery checks BRIDRA_SIDECAR_PATH, the application libexec directory, build/sidecar, then backend/bin. Web builds select the HTTP connector through a conditional import and never import dart:io.

Application-specific methods and response models do not belong in this package. Define those in the consuming application's typed gateway.

Install

flutter pub add bridra_flutter

Common transport

import 'package:bridra_flutter/bridra_flutter.dart';

final client = await connectDefaultRpcClient();
final reply = await client.call('system.health');
await client.close();

Calls accept an optional cancellation token. Timeouts use the same transport cancellation path automatically.

final cancellationToken = RpcCancellationToken();
final reply = client.call(
  'report.build',
  cancellationToken: cancellationToken,
);
cancellationToken.cancel();

Desktop sidecar

Desktop-only code may import the explicit sidecar library:

import 'package:bridra_flutter/bridra_flutter_sidecar.dart';

final client = await SidecarClient.start(
  executablePath: executablePath,
  token: SidecarClient.createToken(),
);
