 # flutter-action
 
-This action sets up a flutter environment for use in actions. It works on Linux, Windows, and macOS.
+Flutter environment for use in GitHub Actions. It works on Linux, Windows, and macOS.
 
-# Usage
+## Usage
+
+Use specific version and channel:
 
 ```yaml
 steps:
-- uses: actions/checkout@v1
-- uses: actions/setup-java@v1
+- uses: actions/checkout@v3
+- uses: subosito/flutter-action@v2
   with:
-    java-version: '12.x'
-- uses: subosito/flutter-action@v1
-  with:
-    flutter-version: '1.9.1+hotfix.6'
-- run: flutter pub get
-- run: flutter test
-- run: flutter build apk
+    flutter-version: '3.7.7'
+    channel: 'stable'
+- run: flutter --version
 ```
 
 Use latest release for particular channel:
 
 ```yaml
 steps:
-- uses: actions/checkout@v1
-- uses: actions/setup-java@v1
+- uses: actions/checkout@v3
+- uses: subosito/flutter-action@v2
   with:
-    java-version: '12.x'
-- uses: subosito/flutter-action@v1
-  with:
-    channel: 'stable' # or: 'dev' or 'beta'
-- run: flutter pub get
-- run: flutter test
-- run: flutter build apk
+    channel: 'stable' # or: 'beta' or 'dev'
+- run: flutter --version
 ```
 
 Use latest release for particular version and/or channel:
 
 ```yaml
 steps:
-- uses: actions/checkout@v1
-- uses: actions/setup-java@v1
+- uses: actions/checkout@v3
+- uses: subosito/flutter-action@v2
   with:
-    java-version: '12.x'
-- uses: subosito/flutter-action@v1
+    flutter-version: '1.22.x'
+    channel: 'dev'
+- run: flutter --version
+```
+
+Use particular version on any channel:
+
+```yaml
+steps:
+- uses: actions/checkout@v3
+- uses: subosito/flutter-action@v2
   with:
-    flutter-version: '1.12.x' # you can use 1.12
-    channel: 'dev' # optional, default to: 'stable'
+    flutter-version: '2.x'
+    channel: 'any'
+- run: flutter --version
+```
+
+Build Android APK and app bundle:
+
+```yaml
+steps:
+- uses: actions/checkout@v3
+- uses: actions/setup-java@v2
+  with:
+    distribution: 'zulu'
+    java-version: '11'
+- uses: subosito/flutter-action@v2
+  with:
+    flutter-version: '3.7.7'
 - run: flutter pub get
 - run: flutter test
 - run: flutter build apk
+- run: flutter build appbundle
 ```

+- run: flutter build web
+```
+
+Build for Windows:
+
+```yaml
+jobs:

+        sudo apt-get install -y ninja-build libgtk-3-dev
+     - run: flutter config --enable-linux-desktop
+     - run: flutter build linux
+```
+
+Build for macOS desktop:
+
+```yaml

+```yaml
+steps:
+- uses: actions/checkout@v3
+- uses: subosito/flutter-action@v2
+  with:
+    channel: 'stable'
+    cache: true
+    cache-key: 'flutter-:os:-:channel:-:version:-:arch:-:hash:' # optional, change this to force refresh cache
+    cache-path: ${{ runner.tool_cache }}/flutter/:channel:-:version:-:arch: # optional, change this to specify the cache path
+    architecture: x64 # optional, x64 or arm64
+- run: flutter --version
+```
+
+Note: `cache-key` and `cache-path` has support for several dynamic values:
+
+- `:os:`
+- `:channel:`
+- `:version:`
+- `:arch:`
+- `:hash:`
+- `:sha256:`
+
+Use outputs from `flutter-action`:
+
+```yaml
+steps:
