部分没有遇到的问题可参考

 接下来列举一下我遇到的问题
1.环境问题
默认项目工程由于gradle版本比较低集成遇到问题 暂未解决 ×
后建立了新的项目 升级了gradle版本。√
2.support 支持
建立新support工程后 集成flutter-boost没有正常编译没有报错 
运行时遇到Androidx 与 support冲突问题 （flutter_boost3.0依赖Androidx）
后升级support项目 至Androidx 解决问题 √
3.flutter SDk 问题 据说新版本有此问题  老版本没有问题
问题描述： flutter升级到最新 运行example_new 出现问题 Activity无法转换为ExclusiveAppComponent<Activity> 
（1）.可以考虑先暂时将 Flutter SDK 切换到2.5.x(不建议调整 flutter sdk版本)
（2）.推荐此方式 作为临时解决方案，可以自己先「造」一个ExclusiveAppComponent，返回正确的Activity

public class FlutterBoostActivity extends FlutterActivity implements FlutterView
     private void performAttach() {
         if (!isAttached) {
             // Attach plugins to the activity.
-            getFlutterEngine().getActivityControlSurface().attachToActivity(getActivity(), getLifecycle());
+            getFlutterEngine().getActivityControlSurface().attachToActivity(delegate, getLifecycle());
 
             if (platformPlugin == null) {
                 platformPlugin = new PlatformPlugin(getActivity(), getFlutterEngine().getPlatformChannel());
public class FlutterBoostFragment extends FlutterFragment implements FlutterView
     private boolean isAttached = false;
     private boolean isFinishing = false;
 
+    class FakeExclusiveAppComponent implements io.flutter.embedding.android.ExclusiveAppComponent<Activity> {
+        public void detachFromFlutterEngine() {
+            // do nothing.
+        }
+
+        public Activity getAppComponent() {
+            return getActivity();
+        }
+    }
+    private FakeExclusiveAppComponent fakeAppComponent = new FakeExclusiveAppComponent();
+

public class FlutterBoostFragment extends FlutterFragment implements FlutterView
     private void performAttach() {
         if (!isAttached) {
             // Attach plugins to the activity.
-            getFlutterEngine().getActivityControlSurface().attachToActivity(getActivity(), getLifecycle());
+            getFlutterEngine().getActivityControlSurface().attachToActivity(fakeAppComponent, getLifecycle());
 
             if (platformPlugin == null) {
                 platformPlugin = new PlatformPlugin(getActivity(), getFlutterEngine().getPlatformChannel());
