It does not matter what the challenges with building a company are; software is (almost) always the solution. At the start of September 2020, I set out to build with 2 of my co-founders. Every time we encountered a problem statement, there was always a SaaS solution to help solve our problem. Felt like someone in the world thought ahead of us all the time. Their work helped speed ours. The best part? To use those SaaS tools, we did not have to shell out a fortune. The low cost made us favor the buy decision in the 'build vs. buy' argument. Zluri In less than ten weeks of company formation, we see ourselves using more than 28 software subscriptions, and we have only five employees, including three co-founders, and our product is not released yet! Employee: Subscription Software ratio is now almost 1:6. I will be tracking how this ratio skews in the months to come as we expand the number of employees and customers. Like my tech co-founder would say, it is time we should have a 'software hiring, onboarding and exit' plan just like a 'talent-hiring, onboarding and exit' plan that has been in existence for a long time :) Before sharing the software stack that we have deployed or about to deploy, I want to share how we make software buying decisions in the current boot-strapped stage of zluri.com, Software that follows the freemium model based on either employee size or API calls or the number of active users is our first choice. It helps us spend $ only when we scale. Software that is part of the start-up ecosystem and offers a time-based, revenue-based, or funding-based discount is our second choice. Software that follows a 14-day or a 30-day trial-based approach is our third choice. Software that does not allow any trial but wants us to pay just after a demo to use it is not a choice unless we have used the software in the past, and buying decision is a no-brainer. From org stack to tech stack, the details are here.

This is not even including the sales stack, customer success stack, and the billing stack that by itself will have 15+ SaaS apps at the minimum. I can already foresee the number of software that we will be using in the next six months to one year and all the hassles that come with managing so many software on my emails and slack! But I got to agree on one thing. If we had not taken this approach of moving to SaaS for our product building and company building, we would have conservatively taken thrice the time to reach where we have got now. In sum, software-first thinking to problem-solving has been empowering to us as an early-stage company, and I can only imagine how world-changing it could be for companies more prominent than ours.

Subscription-based Software (SaaS) is the Panacea for Almost Anything 

How to develop a Bridge in Flutter between Dart and Native Code Flutter allows us to call platform-specific APIs available in Java or Kotlin code on Android and in Objective C or Swift code on iOS. Flutter’s platform-specific API works with message passing. From Flutter app we have to send messages to a host on iOS or Android parts of the app over a platform channel. The host listens on the platform channel and receives the message. It then uses any platform-specific APIs using the native programming language and sends back a response to the Flutter portion of app. Architecture overview Messages are passed between the Flutter Code(UI) and host (platform) using platform channels. Messages and responses are passed asynchronously and the user interface remains responsive. On Dart side using MethodChannel(API) we send a message which is corresponding to a method call. On the Android side MethodChannel Android (API) and on the iOS side FlutterMessageChannel (API) is used for receiving method calls and sending back result. These classes allow us to develop a platform plugin with a very simple code. If required, method calls can also be sent in the reverse direction, with the Android/IOS platform acting as client and method implemented in Dart. Data types supported by Platform Channel The standard platform channel uses standard message codec that supports efficient binary serialization of simple JSON-like values of types boolean, number, String, byte buffer, list, and map. The serialization and deserialization of these values to and from messages happen automatically when we send and receive values. Creating flutter app that calls iOS and Android code Now we will create a flutter app with a method call that will be implemented in Android (Java) and iOS (Objective C) respectively. 1. Create a new app project In a terminal run: flutter create flutter_to_native By default, Flutter supports writing Android code in Java and iOS code in Objective C. If you want to use Kotlin and Swift, create a project with the following command. flutter create -i swift -a kotlin flutter_to_native 2. Create a platform Channel The client and host sides of the channel are connected through the channel name passed in the channel constructor. All channel names used in a single app must be unique. In our example, we are creating the channel name flutter.native/helper class _MyHomePageState extends State<MyHomePage> {
  static const platform = const MethodChannel('flutter.native/helper'); 3. Invoke method on platform Channel Invoke a method on the method channel, specifying the concrete method to call via the String identifier. In the code below, it is helloFromNativeCode String response = "";
  try {
    final String result = await  platform.invokeMethod('helloFromNativeCode');
    response = result;
  } on PlatformException catch (e) {
    response = "Failed to Invoke: '${e.message}'.";
  } Use the returned response to update the user interface state inside setState. setState(() {
  _responseFromNativeCode = response;
}); 4. Create method implementation in Android using java In Android Studio open Flutter app and select the android folder inside it. Open the file MainActivity.java Now we have to create a MethodChannel with the same name that we have created in Flutter App. public class MainActivity extends FlutterActivity {
  private static final String CHANNEL = "flutter.native/helper"; We have to create a MethodCallHandler in onCreate method new MethodChannel(getFlutterView(), CHANNEL).setMethodCallHandler(
        new MethodChannel.MethodCallHandler() {
          @Override
          public void onMethodCall(MethodCall call, MethodChannel.Result result) {
            if (call.method.equals("helloFromNativeCode")) {
              String greetings = helloFromNativeCode();
              result.success(greetings);
            }
          }}); 5. Create method implementation in iOS using Objective C Open the file AppDelegate.m of your Flutter app in Xcode. Now we have to create a FlutterMethodChannel with the same name that we have created in Flutter App. FlutterViewController* controller = (FlutterViewController*)self.window.rootViewController;
        FlutterMethodChannel* nativeChannel = [FlutterMethodChannel
        methodChannelWithName:@"flutter.native/helper"
        binaryMessenger:controller]; Create method call handler [nativeChannel setMethodCallHandler:^(FlutterMethodCall* call, FlutterResult result) {
      if ([@"helloFromNativeCode"  isEqualToString:call.method]) {
      NSString *strNative = [weakSelf helloFromNativeCode];
      result(strNative);
    } else {
    result(FlutterMethodNotImplemented);
  }
}]; Complete Code Android Native code import android.os.Bundle;
import io.flutter.app.FlutterActivity;
import io.flutter.plugin.common.MethodCall;
import io.flutter.plugin.common.MethodChannel;
import io.flutter.plugins.GeneratedPluginRegistrant;

public class MainActivity extends FlutterActivity {
  private static final String CHANNEL = "flutter.native/helper";
  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    GeneratedPluginRegistrant.registerWith(this);
    new MethodChannel(getFlutterView(), CHANNEL).setMethodCallHandler(
            new MethodChannel.MethodCallHandler() {
              @Override
              public void onMethodCall(MethodCall call, MethodChannel.Result result) {
                if (call.method.equals("helloFromNativeCode")) {
                  String greetings = helloFromNativeCode();
                  result.success(greetings);
                }
              }});
  }

private String helloFromNativeCode() {
    return "Hello from Native Android Code";
  }
} iOS native code #include "AppDelegate.h"
        #include "GeneratedPluginRegistrant.h"

@implementation AppDelegate

        - (BOOL)application:(UIApplication *)application
        didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

        FlutterViewController* controller = (FlutterViewController*)self.window.rootViewController;
        FlutterMethodChannel* nativeChannel = [FlutterMethodChannel
        methodChannelWithName:@"flutter.native/helper"
        binaryMessenger:controller];
        __weak  typeof(self) weakSelf = self;
        [nativeChannel setMethodCallHandler:^(FlutterMethodCall* call, FlutterResult result) {
        if ([@"helloFromNativeCode"  isEqualToString:call.method]) {
        NSString *strNative = [weakSelf helloFromNativeCode];
        result(strNative);
        } else {
        result(FlutterMethodNotImplemented);
        }
        }];

        [GeneratedPluginRegistrant  registerWithRegistry:self];
        return [super  application:application didFinishLaunchingWithOptions:launchOptions];
        }
        - (NSString *)helloFromNativeCode {
        return  @"Hello From Native IOS Code";
        }

      final String result = await platform.invokeMethod('helloFromNativeCode');
      response = result;
    } on PlatformException catch (e) {
