Is there a way to get the Cert on runtime?, so I can use it on Restricted Google Maps API Key as Request Header.

Ref: Google Maps API Key Android Restrict Usage

Currently I define it on .env and generate the obfuscated cert using envied package.

import 'package:envied/envied.dart';

part 'envs.g.dart';

/// Environment variables from `.env` file.
@Envied(useConstantCase: true, allowOptionalFields: true)
abstract class Envs {
  /// Decides whether to use hash URL or not on Web.
  @EnviedField()
  static const bool isNoHashUrl = _Envs.isNoHashUrl;

  /// Google Maps API Key for development.
  @EnviedField(defaultValue: '')
  static const String debugGmapsApiKey = _Envs.debugGmapsApiKey;

  /// Android/IOS bundle id.
  @EnviedField()
  static const String appBundleId = _Envs.appBundleId;

  /// Android 20-byte SHA-1 certificate fingerprint.
  ///
  /// Used on Google Maps API Request Header for Restricted API Key.
  /// 
  /// If someone know how to get this on flutter runtime, please let me know.
  @EnviedField(obfuscate: true)
  static final String androidCert = _Envs.androidCert;
}
