Running a Flutter application

Prerequisites

• Build artifacts (engine, embedder)
• Tizen device (Tizen 5.5 or above)
  • Wearable: Fully supported
  • TV: Not supported
• Flutter SDK for Linux
  • https://flutter.dev/docs/get-started/install/linux
• Tizen SDK and IDE
  • Visual Studio (recommended)
  • Visual Studio Code
  • Visual Studio for Mac

How to use

1. Download sample app code from flutter/samples.

2. Choose one of the samples and build.

   cd jsonexample
   flutter create .
   flutter build bundle # add --debug option for Debug build

3. Generate AOT compiled code (for Release build).

   mkdir -p build/linux/aot
   
   # Generate app.dill
   <Flutter SDK root>/bin/cache/dart-sdk/bin/dart \
   <Flutter SDK root>/bin/cache/artifacts/engine/linux-x64/frontend_server.dart.snapshot \
   --sdk-root <Flutter SDK root>/bin/cache/artifacts/engine/common/flutter_patched_sdk_product/ \
   --target=flutter \
   -Ddart.developer.causal_async_stacks=true \
   -Ddart.vm.profile=false \
   -Ddart.vm.product=true \
   --bytecode-options=source-positions \
   --aot \
   --tfa \
   --packages .packages \
   --output-dill build/linux/aot/app.dill \
   --depfile build/linux/aot/kernel_compile.d \
   package:jsonexample/main.dart
   
   # Generate libapp.so
   <Flutter engine root>/src/out/linux_release_arm/clang_x64/gen_snapshot \
   --causal_async_stacks \
   --deterministic \
   --snapshot_kind=app-aot-elf \
   --elf=build/linux/aot/libapp.so \
   --strip \
   --no-sim-use-hardfp \
   --no-use-integer-division \
   build/linux/aot/app.dill

4. Copy files to corresponding directories. (Replace the files that I provided.)

   • From samples/jsonexample
     • build/linux/aot/libapp.so → dotnet-host/lib/armel
     • build/flutter_assets/* → dotnet-host/res/flutter_assets
   • From embedder
     • out/icudtl.dat → dotnet-host/res
     • out/libflutter_engine.so → dotnet-host/lib/armel
     • out/libflutter_embedder.so → dotnet-host/lib/armel

5. Open dotnet-host/FlutterApplication.sln in Visual Studio.

   • The native (C/C++) host will be provided later.

6. Build and run.
