Flutter SDK Docker Images

Minimal, secure Flutter SDK images for CI/CD pipelines. Built on Wolfi for a smaller footprint and zero CVEs.

Images

Variant Use Case Size
svrnty/flutter-sdk:web-latest Web/WASM builds ~800 MB
svrnty/flutter-sdk:android-latest Android APK/AAB builds ~1.7 GB
svrnty/flutter-sdk:linux-latest Linux desktop builds ~1.3 GB

Size Comparison

Image Size
svrnty/flutter-sdk:android 1.7 GB
cirrusci/flutter:stable 4.5 GB
ghcr.io/cirruslabs/flutter:stable 6.8 GB

Up to 75% smaller than alternatives.

Features

  • Zero CVEs - No critical, high, or medium vulnerabilities
  • Multi-arch - Supports both linux/amd64 and linux/arm64
  • Non-root - Runs as unprivileged user (UID 65532)
  • Minimal - Only includes dependencies needed for each platform
  • SBOM & Provenance - Full supply chain attestations included

Usage

Web

docker run --rm -v $(pwd):/app -w /app svrnty/flutter-sdk:web-latest \
  flutter build web

Android

docker run --rm -v $(pwd):/app -w /app svrnty/flutter-sdk:android-latest \

  flutter build linux

CI/CD Examples

GitHub Actions

jobs:
  build:
    runs-on: ubuntu-latest
    container:
      image: svrnty/flutter-sdk:android-latest
    steps:
      - uses: actions/checkout@v4
      - run: flutter build apk --release

GitLab CI

build:
  image: svrnty/flutter-sdk:android-latest
  script:
    - flutter build apk --release

Gitea Actions

jobs:
  build:
    runs-on: ubuntu-latest
    container:
      image: svrnty/flutter-sdk:android-latest
    steps:
      - uses: actions/checkout@v3
      - run: flutter build apk --release
