Embedded Flutter

Joel Winarske

Last update: Dec 28, 2022

Overview

flutter_embedded

This repo is used for CI automation to build flutter-engine embedder for Linux.

Project Status

x86_86 and aarch64 functional

No external toolchain is required, it uses toolchain pulled as part of engine build - Clang Toolchain.

If your are using a sysroot different than that included as default, you will need to override a few variables. See examples below.

The original Yocto Layer to build Engine with variety of Flutter embedders: meta-flutter

Build Example

See CI build jobs here: https://github.com/jwinarske/flutter_embedded/blob/ci/.github/workflows/blank.yml

Switching channels

To switch channels add variable CHANNEL to cmake invocation. Like this

cmake .. -DCHANNEL=beta
make package -j8

To build all channels of Engine/GLFW shell for Raspberry Pi armv7 in your nightly CI build job, you could do this

git clone https://github.com/jwinarske/flutter_embedded
cd flutter_embedded
mkdir build && cd build
cmake ..
make package -j8
cmake .. -DCHANNEL=beta
make package -j8
cmake .. -DCHANNEL=dev
make package -j8
cmake .. -DCHANNEL=master
make package -j8
cmake .. -DCHANNEL=stable -DENGINE_RUNTIME_MODE=release
make package -j8
cmake .. -DCHANNEL=beta
make package -j8
cmake .. -DCHANNEL=dev
make package -j8
cmake .. -DCHANNEL=master
make package -j8

Override Variables

To use the override variables, pass them in with the cmake command. One example

cmake -DTOOLCHAIN_DIR=~/Android/Sdk/ndk-bundle/toolchains/llvm/prebuilt/linux-x86_64 -DTARGET_SYSROOT=~/Android/Sdk/ndk-bundle/toolchains/llvm/prebuilt/linux-x86_64/sysroot  -DENGINE_REPO=https://github.com/jwinarske/engine -DCMAKE_BUILD_TYPE=Release

TARGET_SYSROOT

This is the location of the target sysroot. The default value is "${CMAKE_SOURCE_DIR}/sdk/sysroot". One approach would be to download target image such as a Raspberry Pi image, and mount it. Setting TARGET_SYSROOT to the rootfs directory.

TARGET_ARCH

This is the target architecture of your build. It must match your toolchain, and that which the flutter engine build supports.

ENGINE_REPO

This is the repo of the flutter engine. The default value is https://github.com/flutter/engine.git. If you want to use your own fork, set this variable to point to your fork's url.

ENGINE_UNOPTIMIZED

Unoptimized flag, defaults to OFF

ENGINE_RUNTIME_MODE

If ENGINE_RUNTIME_MODE is not set to debug, profile, or release, it defaults to debug.

ENGINE_SIMULATOR

Enable simulator, defaults to OFF

ENGINE_INTERPRETER

Enable interpreter, defaults to OFF

ENGINE_DART_DEBUG

Enable dart-debug, defaults to OFF

ENGINE_CLANG

Enable clang, defaults to ON

ENGINE_GOMA

Enable goma, defaults to OFF

ENGINE_LTO

Enable link-time optimization, defaults to ON

ENGINE_EMBEDDER_FOR_TARGET

Embedder for Target, defaults to ON

ENGINE_ENABLE_VULKAN

Enable Vulkan, defaults to OFF

Native Flutter Target Debug

I am successfully able to single step the Flutter Embedder using Host Side gdb-multiarch, and latest Eclipse release. Target side requires gdbserver installed. LLDB will be at a later date.

sudo apt-get install gdbserver

Change build flags in this file

{build folder}/engine-prefix/src/engine/src/build/config/compiler/BUILD.gn

To include

if (is_linux) {
    if (current_cpu != "x86") {
        cflags_cc += [ 
        "-ggdb",
        "-ggdb3",

Rebuild Engine

Copy Artifact

Set breakpoint at FlutterEngineRun().

Run the debugger, once breakpoint hits, change to the Debugger Console window, and issue

set step-mode on

Step into FlutterEngineRun()

Touchscreen not working

Hi, I have made it to run in CLI mode with the following outputs: It's on Raspberry Pi 3B with Official 7" Touchscreen I can confirm that the touchscreen works under startx, and if I run flutter under startx, the touch can work, but not under pure CLI mode, can someone advise, thanks!

lubflutter_linux.so not created

Following the build process without mods (except for the --color-diagnostics flag removal).

No issues besides those two hiccups. Any reason libflutter_linux.so wouldn't exist?

Error copying file "/path/to/flutter_embedded/build/engine-prefix/src/engine/src/out/linux_dynamic_release_arm/libflutter_linux.so" to "/path/to/flutter_embedded/build/target/lib".

x86_64 3.x segfault

Segfault is happening in 3.x x86_64 builds on Ubuntu 20.04. aarch64 builds do not exhibit this problem. Ubuntu22 via WSL does not segfault.

Build flags: --unoptimized --runtime-mode debug --no-goma --lto --clang --embedder-for-target --full-dart-sdk --target-os linux --linux-cpu x64 --target-triple x86_64-linux-gnu

Repro happens with or without --unoptimized.

Seg fault happens with: https://github.com/freetype/freetype/blob/3f83daeecb1a78d851b660eed025eeba362c0e4a/src/base/ftobjs.c#L5656

The function that calls it has this note: https://github.com/freetype/freetype/blob/3f83daeecb1a78d851b660eed025eeba362c0e4a/include/freetype/ftcolor.h#L1620

@since: * 2.11 -- currently experimental only! There might be changes without retaining backward compatibility of both the API and ABI.

It looks like it happens when it is trying to display the hello world text: "Futter Demo Home Page" https://github.com/google/skia/blob/main/modules/skparagraph/src/OneLineShaper.cpp#L705
