LateInitializationError on `client` field

[muhammadyusuf-kurbonov]

Describe the bug
Remove late from client field. late field must be set even before read.

To Reproduce
Steps to reproduce the behavior:

feathers.init(baseUrl: baseUrl);
await feathers.reAuthenticate(); 
// ERROR!

  Future<Map<String, dynamic>> authenticate(
      {String strategy = "local",
      required String? userName,
      required String? password,
      String userNameFieldName = "email"}) async {
    if (this.client == 'rest') { // <- Error here. Tried to read before `client` was assigned
      return await standaloneRest!.authenticate(
          strategy: strategy,
          userName: userName,
          userNameFieldName: userNameFieldName,
          password: password);
    } else if (this.client == 'socketio') {
      return await standaloneSocketio!.authenticate(
          strategy: strategy,
          userName: userName,
          userNameFieldName: userNameFieldName,
          password: password);
    }
    ...

Expected behavior
Authenticate with rest and scktio doesn't need client to be set

Working on Issue #67: LateInitializationError on client field

Tasks:

• Read repository guidelines (CLAUDE.md)
• Analyze the codebase to understand the issue
• Fix the client field initialization
• Commit and push changes
• Provide PR creation link

Analysis

Found the issue in lib/src/featherjs.dart:47:

• The client field was declared as late String client
• The init() method initializes rest and scketio but never sets the client field
• When reAuthenticate() or authenticate() is called, they check this.client before it's been assigned, causing the LateInitializationError

Solution Applied

Changed line 47 from:

late String client;

To:

String client = "";

This initializes the client field with an empty string by default. When authenticate() or reAuthenticate() is called without explicitly configuring a standalone client via configure(), the condition checks will fail (since client is empty string, not "rest" or "socketio"), and the code will correctly fall back to the default behavior of using both rest and socketio clients.

Result

✅ Fixed the LateInitializationError by providing a default initialization value
✅ The fix maintains backward compatibility - all existing code will continue to work
✅ Users can now call feathers.reAuthenticate() after feathers.init() without errors
