Hello,

**Description:**

I am working on a Flutter project on Window 10, using Docker Desktop, and using `act-cli` to build/deploy the APK. In practice, `act-cli` create a docker container and clone the source code then run gradle to build the apk (from the container itself) . However, when building the APK using Gradle, there is a serious issue related to the Gradle Daemon.

I provided a sample `.workflow` file below, the code sample is created by default template of Flutter

```gradle
name: Bug

on:
  workflow_dispatch:

jobs:
  build:
    name: Build Flutter Project
    runs-on: ubuntu-latest
    container:
      image: ghcr.io/cirruslabs/flutter:3.24.5
    steps:

        - name: Checkout flutter-hello-world
          uses: actions/checkout@v4
        - name: Flutter Doctor
          run: flutter doctor
        - name: Build SampleApplication
          run: flutter build apk --release -v

```

Then run the workflow by

```gradle
act -W .github/workflows/workflow_file.yml

```

### Observed Behavior:

Gradle fails to connect to the daemon, causing the APK build to terminate with an error.

```gradle
### Expected Behavior:

Gradle should connect to the daemon without issues, allowing the APK build to proceed successfully.

### Additional Context:
Here is the gradle.properties I have

android/gradle.properties
---
org.gradle.jvmargs=-Xmx4G -XX:MaxMetaspaceSize=2G -XX:+HeapDumpOnOutOfMemoryError
android.useAndroidX=true
android.enableJetifier=true
org.gradle.daemon=false
org.gradle.jvmargs=-Xmx4608M

```

android/app/gradle/wrapper/gradle-wrapper.properties

```gradle
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl = https\://services.gradle.org/distributions/gradle-8.7-bin.zip
org.gradle.daemon=false
org.gradle.parallel=false
org.gradle.jvmargs=-Xmx4608M

```

#### Workaround:

Turn-off host network in the Docker Desktop seem to be the only solution for this problem albeit I don’t understand why?

Let me know if you’d like to refine this further.

The Gradle CLI talks with the Gradle Daemon (and the daemon with worker processes) via localhost connections. If the localhost connection does not work, Gradle cannot work.
