…GL version strings Some versions of the Android emulator EGL implementation will only update the GL_VERSION string when the process calls eglMakeCurrent on an EGLContext for the first time. If you select a GLES2 context, then a GLES1 context, and then the original GLES2 context, the version string will not be updated by the second eglMakeCurrent(GLES2) call. So if a GLES1 context was previously current, then when the engine makes its GLES2 context current Skia will continue to see the GLES1 version string and will fail to build a GrGLInterface. This workaround checks for the emulator GL renderer and creates a new context to force a version string update before making the GrGLInterface. See internal bug b/168748787 Fixes flutter/flutter#63663

Some versions of the Android emulator EGL implementation will only
update the GL_VERSION string when the process calls eglMakeCurrent
on an EGLContext for the first time. If you select a GLES2 context,
then a GLES1 context, and then the original GLES2 context, the version
string will not be updated by the second eglMakeCurrent(GLES2) call.
So if a GLES1 context was previously current, then when the engine makes
its GLES2 context current Skia will continue to see the GLES1 version
string and will fail to build a GrGLInterface.
This workaround checks for the emulator GL renderer and creates a new
context to force a version string update before making the
GrGLInterface.
