Use case

From issue #132402

When initalRoute is mentioned in MainActivity.kt, GoRouter's initalRoute doesn't work. Implemeneted in 2275

package com.example.go_route.test_go_route

import io.flutter.embedding.android.FlutterActivity

class MainActivity: FlutterActivity() {
    override fun getInitialRoute(): String? {
        return "/home"
    }

}

Proposal

Implement a new optional bool parameter such as overridePlatformDefaultLocation, which would override platform set initial location.
