'Flutter/Flutter.h' file not found

[borisverbitckii]

I'm trying to run a demo application, but I keep encountering the issue that Flutter/Flutter.h cannot be found.

I've downloaded two archives to run the application on a tvOS simulator:

• host_debug_unopt_arm64
• ios_debug_sim_unopt_arm64

3.19.6 and 3.16.9

I've tried setting the FLUTTER_LOCAL_ENGINE in different ways:

export FLUTTER_LOCAL_ENGINE=/Users/borisverbitskii/Desktop/engine/src export FLUTTER_LOCAL_ENGINE=/Users/borisverbitskii/Desktop/engine In this case, the downloaded files were unpacked in these paths.

export FLUTTER_LOCAL_ENGINE=/Users/borisverbitskii/Desktop/engine/src/host_debug_unopt_arm64 export FLUTTER_LOCAL_ENGINE=/Users/borisverbitskii/Desktop/engine/src/ios_debug_sim_unopt_arm64 In this case, I pointed to the specific folders of the downloaded files.

===========================

I have an M1 Mac, so I use the command:

sh scripts/run_apple_tv.sh debug_sim_arm64

===========================

Here is my main Flutter version:

Any idea what I'm doing wrong?

[DenisovAV]

Hello, at this moment the last supported flutter version is 3.19.6, you should install fvm and switch your flutter version for the project to 3.19.6

so you need to download only 3.19.6 engine and unzip it to Users/borisverbitskii/Desktop/engine/src/out folder

please check all steps and try again

[jtkeyva]

you keep talking about this 'out' folder? what do you mean?

i download a zip file, can't i jsut set the path to my download folder and then the name of the folder? ios_debug_sim_unopt_arm64

like can't this be ok?

export FLUTTER_LOCAL_ENGINE=/Users/me/code/apple-tv/flutter/ios_debug_sim_unopt_arm64

i have fvm installed and using 3.24.1

i am getting same error: 'Flutter/Flutter.h' file not found

please help thanks

[DenisovAV]

Hi, you should unzip the files ios_debug_sim_unopt_arm64 and host_debug_unopt_arm64 to '/Users/me/code/apple-tv/flutter/out' folder and then update run_appletv.sh - export FLUTTER_LOCAL_ENGINE=/Users/me/code/apple-tv/flutter

[jtkeyva]

thank you.. buti am still getting the same error. i see this error in terminal:

• sh ../scripts/copy_framework.sh debug_sim_arm64 /Users/me/code/apple-tv/flutter Coping Flutter.framework (debug-simulator-arm64)... cp: /Users/me/code/apple-tv/flutter/out/ios_debug_sim_unopt_arm64/clang_x64/../Flutter.framework: No such file or directory
• sed -i '' 's#FLUTTER_LOCAL_ENGINE[[:space:]]=[[:space:]].*;#FLUTTER_LOCAL_ENGINE = "/Users/me/code/apple-tv/flutter";#g' Runner.xcodeproj/project.pbxproj
• open Runner.xcworkspace

[DenisovAV]

Are you trying with 3.24.1 ?

[jtkeyva]

yes thanks. but what is the engine folder? and the src folder? i don't understand what that is or how to get it?

[DenisovAV]

In my case 'engine' folder is root folder for everything, 'engine/src' is folder of source code of engine, 'engine/src/out' is folder for compiled engine. You don't need source code, but you need to have the same structure, so you need to unzip compiled engine to 'your_folder/out' and set up the path 'export FLUTTER_LOCAL_ENGINE=/Users/your_name/full_path/your_floder'

[jtkeyva]

thank you. i don't know why this is so hard for me to figure out. what engine are you talking about? is one of the zip files you had the compiled engine? or do i need to get the compiled engine from somewhere else?

here's what i am doing:

i download host_debug_unopt_arm64.zip and extract to /Users/me/flutter-apple-tv-test so there is /Users/me/flutter-apple-tv-test/host_debug_unopt_arm64

i download ios_debug_sim_unopt_arm64.zip and extact to /Users/me/flutter-apple-tv-test so there is /Users/me/flutter-apple-tv-test/ios_debug_sim_unopt_arm64

i download/clone flutter-tv and extract to /Users/me/flutter-apple-tv-test so i have /Users/me/flutter-apple-tv-test/flutter-tv

then i modify the script to FLUTTER_LOCAL_ENGINE=/Users/me/flutter-apple-tv-test/out'

am i missing something here? thanks!

[DenisovAV]

1) Extract host_debug_unopt_arm64.zip to /Users/me/flutter-apple-tv-test/out/ there will be /Users/me/flutter-apple-tv-test/out/host_debug_unopt_arm64 2) Extract ios_debug_sim_unopt_arm64.zip to /Users/me/flutter-apple-tv-test/out/ there will be /Users/me/flutter-apple-tv-test/out/ios_debug_sim_unopt_arm64 3) Clone flutter_tv to /Users/me/flutter-apple-tv-test there will be /Users/me/flutter-apple-tv-test/flutter-tv 4) Modify FLUTTER_LOCAL_ENGINE=/Users/me/flutter-apple-tv-test 5) Then run sh scripts/run_appletv.sh from Users/me/flutter-apple-tv-test/flutter-tv folder

[jtkeyva]

Perfect thank you, it works!

[DenisovAV]

Great! Good luck with your application

[jtkeyva]

Thank you
