If you’re getting hung up on either trying to figure out how to set up your launch screen on Android by following the Flutter docs or having issues with the image scaling, try this quick guide on getting it to work as you intend.

I created a new Flutter project and also a PNG image I will use on the launch screen:

You may already know that images can contain sensitive information such as GPS coordinates of where the image was taken. This information is stored in the image’s metadata, also known as the EXIF (Exchangeable Image File Format) data. Depending on your use-case, of course, it is a good idea to delete this information before you store it for the world to access.

You will want to check with your storage medium first, as they may already strip all metadata from any file that is uploaded via their services. However, some platforms, such as Google Cloud Storage, do not remove metadata…

You may be wondering if you can integrate Firebase’s anonymous authentication in your application and still maintain some level of persistence (and security) with your back-end. This article details what happens to anonymous authentication credentials after performing different actions with the app.

Here’s the TL;DR summary:

Closing the app and re-opening it from the emulator: Persists

Closing the app and re-running it from the IDE: Persists

Signing in anonymously multiple times: Persists

Signing out and signing back in: Does not Persist

Deleting the app’s cache: Persists

Deleting the app’s data (storage): Does not Persist

Using shared_preferences and clearing its data…

Installing an SSL certificate on your website hosted with FranTech is a pretty straightforward process, but it can be a bit confusing on your first run. Here I’ll walk you through the steps for getting your certificate installed.

You’re going to hit some errors if you just try to issue a certificate via Let’s Encrypt™ SSL if you haven’t done some configuration first — so let’s get to that configuring now.

You’re probably upgrading because you’ve been getting those emails from Google about the Fabric Crashlytics deprecation occurring on November 15, 2020. If you’re running into some problems while upgrading, try the steps listed here.

Step 1 — Follow the Migration Guide

If you are just beginning the upgrade, skip this article and follow the Migration Guide. Following that guide should solve 99 percent of the problems you’ll encounter if you try to migrate without guidance.

Keep in mind that once you upgrade the Crashlytics plugin, you will likely see a host of problems occur due to other incompatible Firebase plugins. So upgrading Crashlytics most likely won’t be…

TL;DR: Be sure you have filled out the information in the “Basic” section of “Settings”

I recently noticed that the Facebook API may not always give you a reason why your app isn’t switching to “Live Mode” from “In Development.” In my case, it just showed a circular progress indicator and then disappeared after a few seconds — no guidance or warning on why.

If this is happening to you, it should be a simple fix:

1. Go to your Facebook Developer page and login
2. When you try to switch the “In development” toggle to put it on “Live,” this is…

After seeing a ton of different answers about changing the splash color of different widgets, namely ListTile, here are two quick ways of doing it:

Be sure to check your specific widget, as some (such as RaisedButton and IconButton) already have splashColor and highlightColor properties you can set without having to modify or add a Theme.

Option 1: Set it in your app’s ThemeData

Caveat: This option will change ALL widgets using splashColor or highlightColor to the colors you set, so if that doesn’t work for you, go for Option 2.

1. In your main.dart file, add ThemeData to your MaterialApp ‘s theme property (if it isn’t already there).
2. …

Want to give some type of dialog in response to an action but the provided Tooltip class just isn’t doing it for you? Maybe it’s time to look at implementing an OverlayEntry.

What is a tool tip?

A tool tip is generally a static text label that appears over something on your screen that provides more insight into what that something does. Some widgets come out of the box with a tooltip property that you can set:
