What it does
Frb Docker is an agent skill from fzyzcjy/flutter_rust_bridge. Use for ordinary flutterrustbridge Docker/devcontainer setup, local image usage, and Apple Silicon containers; route image upgrades and publishing to frb-upgrade-docker.
Its SKILL.md is about 910 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in DevOps & Cloud, covering Containers and Cross-platform mobile apps. It works with Docker, Flutter, Rust and Linux. The repository describes itself as: Flutter/Dart <- Rust binding generator, feature-rich, but seamless and simple. The licence is MIT.
When your agent uses it
- Ordinary flutterrustbridge Docker/devcontainer setup
- Local image usage
- Apple Silicon containers
- Route image upgrades and publishing to frb-upgrade-docker
Example prompts
- “/frb-docker”
Requirements
- Docker
What it can do on your machine
Read from SKILL.md and the folder at commit 848e438. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
dockercargoflutterdartnodenpm
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use docker and npm, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Frb Docker loads about 914 tokens when it runs. Until then it costs about 46 tokens; SKILL.md has 298 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

FRB Docker
Use this skill for ordinary FRB Docker/devcontainer work: local container usage, Apple Silicon behavior, and local Dockerfile validation.
Read frb-upgrade-docker before changing toolchain inputs or publishing fzyzcjy/flutter_rust_bridge_dev. It owns
PR boundaries, candidate tags, stable-tag promotion, and registry workflow policy.
Source of Truth
- Devcontainer config:
.devcontainer/devcontainer.json - Dockerfile:
.devcontainer/Dockerfile - Publish workflow:
.github/workflows/publish_dev_docker.yaml - Published image:
fzyzcjy/flutter_rust_bridge_dev
The Dockerfile is the source of truth for tool versions. Derive image tags from its ARG values instead of hardcoding stale versions.
Daily Local Use
Devcontainer
Prefer devcontainer for normal development.
Dev Containers: Reopen in ContainerThe devcontainer builds from .devcontainer/Dockerfile and runs ./frb_internal pub-get-all to prepare Dart/Flutter package dependencies; first Rust/wasm builds may still be slow because crate compilation caches are not warmed.
Published Image
Default behavior is still to build locally from .devcontainer/Dockerfile. If you want to use a prebuilt image instead, switch to the full version tag derived from the current Dockerfile args rather than latest.
docker run --rm -it -v "$PWD:/workspace" -w /workspace fzyzcjy/flutter_rust_bridge_dev:latest bashUse latest only for quick local checks where reproducibility does not matter.
Manual Docker Build
Use this when not using VS Code devcontainers, or when validating local Dockerfile changes.
docker build -f .devcontainer/Dockerfile -t frb-dev .devcontainer
docker run --rm -it -v "$PWD:/workspace" -w /workspace frb-dev bashInside a fresh manual container, run:
./frb_internal pub-get-allThen run normal development commands such as:
./frb_internal lint
cargo checkApple Silicon
Apple Silicon Macs use the same commands as other platforms. Do not add --platform linux/amd64 for normal local development.
Docker should select linux/arm64 automatically for multi-arch images. If a command only works with --platform linux/amd64, treat that as a regression to investigate.
Local Dockerfile Validation
For Dockerfile changes, validate at least:
docker build -f .devcontainer/Dockerfile -t frb-dev .devcontainer
docker run --rm -v "$PWD:/workspace" -w /workspace frb-dev bash -lc './frb_internal --help'For environment changes, smoke-test the installed tools:
docker run --rm -v "$PWD:/workspace" -w /workspace frb-dev bash -lc '
set -euo pipefail
flutter --version
dart --version
node --version
npm --version
cargo --version
wasm-pack --version
"${CHROME_BIN}" --version
'For broader confidence, run:
docker run --rm -v "$PWD:/workspace" -w /workspace frb-dev bash -lc './frb_internal pub-get-all && ./frb_internal lint --fix'
docker run --rm -v "$PWD:/workspace" -w /workspace/frb_rust frb-dev bash -lc 'cargo check && cargo check --target wasm32-unknown-unknown'If generated files drift during lint/codegen, do not manually edit generated files. Restore unrelated generated drift unless the task intentionally changes generation outputs.
Do not publish from this ordinary-use workflow. Continue with frb-upgrade-docker when validation must produce a
candidate or stable registry image.
