run flutter doctor -v and install the missing packages.

flutter doctor -v

    • clang version 16.0.6
    • cmake version 3.27.6
    • ninja version 1.11.1
    • pkg-config version 0.29.2

or just install all these

i'm using termux gui (not proot), still got the error...

apt install gtk3 doesn't work?

when i created new project i get warning capture-2023-10-24-16-50-14

it does't matter [flutter doctor] Could not determine java version with JDK 21

openjdk17 is provided by Termux but flutter cannot parse it's version.

java --version

openjdk 17-internal 2021-09-14
OpenJDK Runtime Environment (build 17-internal+0-adhoc..src)
OpenJDK 64-Bit Server VM (build 17-internal+0-adhoc..src, mixed mode)

flutter accepts version string like openjdk 17.xx instead of openjdk 17-internal

gtk3 is already the newest version

[mumumusuc]

does pkg-config --libs gtk+-3.0 works?

please run flutter run -d linux -v at hello_world for more debug message.

Thank you very much.

@mumumusuc I am facing the same issue:

"libepoxy.so" not found: needed by /home/user/hello_world/linux/flutter/ephemeral/libflutter_linux_gtk.so

I am on Flutter 3.16.5. Do I need to downgrade it and if yes how? 3.15 which is mentioned by @jongbatax is not in the stable channel.

@fotiDim libepoxy should be automatically installed while installing gtk3, install it manually by apt install libepoxy.

please refer to the install section about dependencies.

@mumumusuc I made a fresh install and now I am getting:

@fotiDim This project is not for proot-distro, just launch it on Termux. Additional, proot-distro can use official flutter instead of this repo.
