如何将instabug SDK集成到flutter应用程序中

Question

我试图在我的android flutter应用程序中实现Instabug (崩溃分析)，但我不知道应该在哪里输入这些代码到我的项目中。

在Application子类的onCreate()方法中初始化Instabug：

flutter包中Application子类的onCreate()方法在哪里？如果我需要创建一个，我应该在哪里创建呢？

Answer 1

在flutter应用程序根目录中，

沿着android/app/src/main/kotlin/your package/走，然后你会看到MainActivity。

只需在MainActivity的相同路径中创建一个继承自FlutterApplication的类

class CustomApplication : FlutterApplication {
    override fun onCreate() {
        super.onCreate()
        // Paste here the integration codes of instabug
    }
}

然后转到清单、android/app/src/main/kotlin/your package/AndroidManifest.xml和修改应用程序部分

<application
   android:name=".CustomApplication"
   ...
</application>

Answer 2

您可以使用package https://pub.dev/packages/instabug_flutter

对于Android，请按照Readme中提到的步骤操作

步骤1:将以下Maven库添加到您的项目级build.gradle

allprojects {
    repositories {
        maven {
            url "https://sdks.instabug.com/nexus/repository/instabug-cp"
        }
    }
}

步骤2:创建一个扩展FlutterApplication的新Java类并将其添加到您的AndroidManifest.xml中。

<application
    android:name=".CustomFlutterApplication"
    ...
</application>

步骤3:在新创建的CustomFlutterApplication类中，覆盖onCreate()并添加以下代码。

来自https://github.com/Instabug/Instabug-Flutter/blob/master/example/android/app/src/main/java/com/instabug/instabugflutterexample/CustomFlutterApplication.java的CustomFlutterApplication代码

package com.instabug.instabugflutterexample;

import io.flutter.app.FlutterApplication;
import com.instabug.instabugflutter.InstabugFlutterPlugin;

import java.util.ArrayList;

public class CustomFlutterApplication extends FlutterApplication {
  @Override
  public void onCreate() {
    super.onCreate();
    ArrayList<String> invocation_events = new ArrayList<>();
    invocation_events.add(InstabugFlutterPlugin.INVOCATION_EVENT_FLOATING_BUTTON);
    InstabugFlutterPlugin instabug = new InstabugFlutterPlugin();
    instabug.start(CustomFlutterApplication.this, "2d355f559ea67051a56fce82603f8e41", invocation_events);
    instabug.setWelcomeMessageMode("WelcomeMessageMode.disabled");
  }
}

Dart示例代码片段https://github.com/Instabug/Instabug-Flutter/blob/master/example/lib/main.dart

import 'dart:async';
import 'dart:io' show Platform;
import 'package:flutter/material.dart';
import 'package:instabug_flutter/Instabug.dart';
import 'package:instabug_flutter/BugReporting.dart';
import 'package:instabug_flutter/Surveys.dart';
import 'package:instabug_flutter/FeatureRequests.dart';
import 'package:instabug_flutter/CrashReporting.dart';

void main() async {
  FlutterError.onError = (FlutterErrorDetails details) {
    Zone.current.handleUncaughtError(details.exception, details.stack);
  };

  runZoned<Future<void>>(() async {
    runApp(MyApp());
  }, onError: (dynamic error, StackTrace stackTrace) {
    CrashReporting.reportCrash(error, stackTrace);
  });
}

class MyApp extends StatefulWidget {
  @override
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  String _platformVersion = 'Unknown';

  @override
  void initState() {
    super.initState();
    if (Platform.isIOS) {
      Instabug.start('efa41f402620b5654f2af2b86e387029',
          <InvocationEvent>[InvocationEvent.floatingButton]);
    }
    initPlatformState();
  }

Answer 3

在深入研究了他们在instabug github repo上的示例后，我能够解决这个问题。

示例应用程序在main/kotlin/com//

1. 下创建一个新的java文件CustomFlutterApplication.java。这就是MainActivity.kt存在的地方。

    package com.example.app;
    
    import io.flutter.app.FlutterApplication;
    import com.instabug.instabugflutter.InstabugFlutterPlugin;
    
    import java.util.ArrayList;
    
    public class CustomFlutterApplication extends FlutterApplication {
      @Override
      public void onCreate() {
        super.onCreate();
        ArrayList<String> invocationEvents = new ArrayList<>();
        invocationEvents.add(InstabugFlutterPlugin.INVOCATION_EVENT_SHAKE);
        new InstabugFlutterPlugin().start(CustomFlutterApplication.this, "<API KEY>", invocationEvents);
      }
    }

在您的AndroidManifest.xml中使用

1. ，用android:name=".CustomFlutterApplication"

替换android:name="io.flutter.app.FlutterApplication"

1. In your project level build.gradle，

(在您的项目级build.gradle中使用)

    allprojects {
        repositories {
            maven {
                url "https://sdks.instabug.com/nexus/repository/instabug-cp"
            }
        }
    }

1. 现在生成您的项目
