1. I create PROD environment in Github.

2. I add Environment secrets as below.

3. I will fetch these keys with String.fromEnvironment.

class _HomeState extends State<Home> {
  @override
  Widget build(BuildContext context) {
    const supabaseUrl =
        String.fromEnvironment('envkey_SUPABASE_URL', defaultValue: "check1");
    const supabaseAnonKey = String.fromEnvironment('envkey_SUPABASE_ANONKEY',
        defaultValue: "check2");
    return const Scaffold(
      body: Row(
        children: [
          Column(
            children: [
              Text("check"),
              Text(supabaseUrl),
              Text(supabaseAnonKey),
            ],
          ),
        ],
      ),
    );
  }
}

4. I deploy flutter web with Github Actions in .github/workflows/workflow.yml.

I create environment file with SpicyPizza/[email protected].

name: gh-pages

on:
  push:
    branches: [main]
jobs:

  PROD:
      runs-on: ubuntu-latest
      environment: PROD
      steps:
        - uses: actions/checkout@v2
        - name: Create environment file
          uses: SpicyPizza/[email protected]
          with:
            envkey_SUPABASE_URL: ${{ secrets.SUPABASE_URL }}
            envkey_SUPABASE_ANONKEY: ${{ secrets.SUPABASE_ANONKEY }}
        - uses: subosito/flutter-action@v1
        - uses: bluefireteam/flutter-gh-pages@v7
          with:
            baseHref: /injicare-event/

Build is done successfully.

However, deployed site shows default value from String.fromEnvironment, which means i can’t fetch keys from environment.

I’ve also added Repository secrets either as below..

I’ve struggled with this problem for more 2 months.

I’ve done all as all searched document say, but nothing works..

Please help me..!!!! T_T
