flutter v1.12.13+hotfix.5 华为畅想9闪退

Question

跪求解决方案！！！
机型：华为畅想9
操作系统：安卓8.2.0
flutter_sdk ：v1.12.13+hotfix.5
webview_flutter: ^0.3.18+1

场景：启动闪退
错误代码：

E/flutter (17642): [ERROR:flutter/shell/gpu/gpu_surface_gl.cc(70)] Failed to setup Skia Gr context.
Error connecting to the service protocol: failed to connect to http://127.0.0.1:55401/KPoJi4ijsMg=/

尝试方案：
在MainActivity中增加getIntent().putExtra("enable-software-rendering", true);
这样确实可以启动了

新的问题：
修改后打开webview闪退
错误代码：

E/flutter (19801): [ERROR:flutter/shell/platform/android/platform_view_android_jni.cc(39)] java.lang.RuntimeException: Error during attachToGLContext (see logcat for details)
E/flutter (19801): at android.graphics.SurfaceTexture.attachToGLContext(SurfaceTexture.java:300)
E/flutter (19801):
F/flutter (19801): [FATAL:flutter/shell/platform/android/platform_view_android_jni.cc(123)] Check failed: CheckException(env).

各位大佬，走到这里，小弟真的不知道该如何解决了，没学过android和ios原生，走到这里全靠各种百度的flutter内容
