Android FlutterBoost开启FlutterBoostFragment页面导致状态栏颜色异常

[JunhuaLin]

问题背景：
我司App支持黑白两色皮肤，关闭Flutter引擎针对Android一端自动修改状态栏颜色功能后，FlutterBoostFragment页面在白色皮肤下展示了白色的状态栏图标。

问题原因：
由于引擎自动修改状态栏颜色不可控，故我们关闭了Flutter引擎中自动改变状态栏颜色的逻辑，关闭代码如下：

class CustomFBFlutterBinding extends WidgetsFlutterBinding
    with BoostFlutterBinding {
  @override
  void initInstances() {
    super.initInstances();
    // 不自动改变状态栏,关闭引擎中的设置
    renderView.automaticSystemUiAdjustment = false;
  }
}

但是发现关闭Flutter引擎中的自动改变状态栏逻辑后，状态栏颜色依然不可控，最终排查定位到，在FlutterBoostFragment#onResume方法中，调用了platformPlugin.updateSystemUiOverlays()方法导致状态栏显示异常，源码如下：

public class FlutterBoostFragment extends FlutterFragment implements FlutterViewContainer {

@Override
    public void onResume() {
        super.onResume();
        if (Build.VERSION.SDK_INT == Build.VERSION_CODES.Q) {
            final FlutterContainerManager containerManager = FlutterContainerManager.instance();
            FlutterViewContainer top = containerManager.getTopActivityContainer();
            boolean isActiveContainer = containerManager.isActiveContainer(this);
            if (isActiveContainer && top != null && top != this.getContextActivity() && !top.isOpaque() && top.isPausing()) {
                Log.w(TAG, "Skip the unexpected activity lifecycle event on Android Q. " +
                        "See https://issuetracker.google.com/issues/185693011 for more details.");
                return;
            }
        }

        stage = LifecycleStage.ON_RESUME;
        if (!isHidden()) {
            didFragmentShow();
            getFlutterEngine().getLifecycleChannel().appIsResumed();
        }

        // Update system UI overlays to match Flutter's desired system chrome style
        Assert.assertNotNull(platformPlugin);
        //  此方法调用导致状态栏图标颜色异常，希望独立该方法调用，方便子类重写定制逻辑
        platformPlugin.updateSystemUiOverlays();
        if (DEBUG) Log.d(TAG, "#onResume: " + this);
    }

}

解决方案：
希望独立该platformPlugin.updateSystemUiOverlays()方法调用，方便子类重写定制逻辑。

修改建议方案如下代码：

public class FlutterBoostFragment extends FlutterFragment implements FlutterViewContainer {

@Override
    public void onResume() {
        super.onResume();
        if (Build.VERSION.SDK_INT == Build.VERSION_CODES.Q) {
            final FlutterContainerManager containerManager = FlutterContainerManager.instance();
            FlutterViewContainer top = containerManager.getTopActivityContainer();
            boolean isActiveContainer = containerManager.isActiveContainer(this);
            if (isActiveContainer && top != null && top != this.getContextActivity() && !top.isOpaque() && top.isPausing()) {
                Log.w(TAG, "Skip the unexpected activity lifecycle event on Android Q. " +
                        "See https://issuetracker.google.com/issues/185693011 for more details.");
                return;
            }
        }

        stage = LifecycleStage.ON_RESUME;
        if (!isHidden()) {
            didFragmentShow();
            getFlutterEngine().getLifecycleChannel().appIsResumed();
        }

        // Update system UI overlays to match Flutter's desired system chrome style
        onUpdateSystemUiOverlays();
        if (DEBUG) Log.d(TAG, "#onResume: " + this);
    }

    /**
     * 方便子类修改
     */
    protected void onUpdateSystemUiOverlays(){
        Assert.assertNotNull(platformPlugin);
        platformPlugin.updateSystemUiOverlays();
    }

}
