Step 1. パッケージをインストールする

https://pub.dev/packages/nativebrik_bridge にパッケージが公開されています。

以下のコマンドを実行してパッケージをインストールしてください。

Terminal

flutter pub add nativebrik_bridge

または、直接pubspec.yamlを編集し、pub getを実行することでもインストールできます。

pubspec.yaml

dependencies:
  nativebrik_bridge: ^0.10.6

Terminal

flutter pub get

---

Step 2. Nativebrik SDKを初期化する

main.dart

import 'package:nativebrik_bridge/nativebrik_bridge.dart';
import 'package:nativebrik_bridge/provider.dart';
import 'package:nativebrik_bridge/user.dart';

// ...

void main() {
  WidgetsFlutterBinding.ensureInitialized();

  // Initialize Nativebrik Client
  NativebrikBridge("<PROJECT_ID>");

  // Run your app
  runApp(const MyApp());
}

class _YourAppState extends State<YourApp> {
  @override
  void initState() {
    if (!mounted) return;

    // Set user's properties to use them in the nativebrik experiment
    final user = NativebrikUser();
    await user.setProperties({
      'prefecture': "Tokyo",
      'environment': const bool.fromEnvironment('dart.vm.product')
          ? 'production'
          : 'development',
    });
  }

  @override
  Widget build(BuildContext context) {
    // Add NativebrikProvider to your root widget
    return NativebrikProvider(
      child: MaterialApp(
        // ...
      ),
    );
  }
}

Step 3.a (Android only) Set up Platform Specific Code

To get it working on Android, you need to make a small change to your MainActivity.kt file.

MainActivity.kt

package com.example.app

import io.flutter.embedding.android.FlutterFragmentActivity

// 1. Extend FlutterFragmentActivity instead of FlutterActivity
class MainActivity: FlutterFragmentActivity()

and, set the minimum android sdk version to 26 in your android/app/build.gradle file.

android/app/build.gradle

android {
    defaultConfig {
        // Set the minimum sdk version to 26
        minSdkVersion 26
    }
}

finally, set the kotlin version to >= 1.9.10 in your settings.gradle file.

settings.gradle

plugins {
    // ...
    id "org.jetbrains.kotlin.android" version "1.9.10" apply false
}

Step 3.b. (iOS only) Set up Platform Specific Code

To get it working on iOS, you need to change a minimum deployments to 15.0 in your ios/Runner.xcodeproj/project.pbxproj file.

1. In Xcode, navigate to Runner.xcodeproj > TARGETS > Runner > General > Minimum Deployments

2. Change the minimum deployments to 15.0

Once you're finished, you can start using Nativebrik.
