Flutter - flutter_boost集成踩坑（修改源码

flutter_boost分支：v1.17.1-hotfixes

Android

• 修复：跳转到flutter的webview页面后返回崩溃和webview中无法进行编辑的情况

XTextInputPlugin.java文件 222行

        if (inputTarget.type == InputTarget.Type.PLATFORM_VIEW) {
            if (isInputConnectionLocked) {
                return lastInputConnection;
            }
            lastInputConnection = platformViewsController.getPlatformViewById(inputTarget.id).onCreateInputConnection(outAttrs);
            return lastInputConnection;
        }

修改为以下代码：

        if (inputTarget.type == InputTarget.Type.PLATFORM_VIEW) {
            if (isInputConnectionLocked) {
                return lastInputConnection;
            }
            if (platformViewsController != null && platformViewsController.getPlatformViewById(inputTarget.id) != null) {
                lastInputConnection = platformViewsController.getPlatformViewById(inputTarget.id).onCreateInputConnection(outAttrs);
            } else {
                return lastInputConnection;
            }
            return lastInputConnection;
        }

• 修复：从flutter的webview页面跳转到页面返回后webview无法滑动、交互的问题

FlutterActivityAndFragmentDelegate.java文件 237行

        if(ACTIVITY_CONTROL_SURFACE_ATTACH_TO_ACTVITY_HASH_CODE!=0||
                ACTIVITY_CONTROL_SURFACE_ATTACH_TO_ACTVITY_HASH_CODE==this.host.getActivity().hashCode()){
            flutterEngine.getActivityControlSurface().detachFromActivityForConfigChanges();
        }

注释掉

//        if(ACTIVITY_CONTROL_SURFACE_ATTACH_TO_ACTVITY_HASH_CODE!=0||
//                ACTIVITY_CONTROL_SURFACE_ATTACH_TO_ACTVITY_HASH_CODE==this.host.getActivity().hashCode()){
//            flutterEngine.getActivityControlSurface().detachFromActivityForConfigChanges();
//        }

iOS

• 修复：flutter作为tabbar的根视图互相切换时会有明显的闪屏

FLBFlutterViewContainer.m文件 285行

if([UIApplication sharedApplication].applicationState == UIApplicationStateActive){
        //NOTES：务必在show之后再update，否则有闪烁; 或导致侧滑返回时上一个页面会和top页面内容一样
        [self surfaceUpdated:YES];
}

修改为：

    if([UIApplication sharedApplication].applicationState == UIApplicationStateActive){
        //NOTES：务必在show之后再update，否则有闪烁; 或导致侧滑返回时上一个页面会和top页面内容一样
//        [self surfaceUpdated:YES];
        
        /// 延迟刷新 避免闪屏
        __block FlutterViewController *weakSelf = self;
        dispatch_time_t delayTime = dispatch_time(DISPATCH_TIME_NOW, (int64_t)(.1 * NSEC_PER_SEC));
        dispatch_after(delayTime, dispatch_get_main_queue(), ^{
            [weakSelf surfaceUpdated:YES];
        });
    }

目前所有修改不确保稳定、仅为解决刚性问题临时方案
