Issue 1:
Steps to Reproduce

Upon loading asset image (on some phones, in some side state), the flutter engine hangs, while actual process continues to execute. Sometimes, Android produces ANR error.

I am on v0.3.0. If I switch to beta I get compilation error:

Initializing gradle... 1.0s
Resolving dependencies... 0.9s
Running 'gradlew assembleDebug'...

Investigation

Seems to hang in engine engine.cc on line 416

void Engine::HandleAssetPlatformMessage(
fxl::RefPtr<blink::PlatformMessage> message) {
fxl::RefPtr<blink::PlatformMessageResponse> response = message->response();
if (!response) {
return;
}
const auto& data = message->data();
std::string asset_name(reinterpret_cast<const char*>(data.data()),
data.size());

std::vector<uint8_t> asset_data;
// !!! hangs on GetAsBuffer() call !!!
if (asset_manager_ && asset_manager_->GetAsBuffer(asset_name, &asset_data)) {
response->Complete(std::move(asset_data));
} else {
response->CompleteEmpty();
}
}
