A month of Flutter: upgrading to 1.0

Originally published on
Yesterday's announcement of Flutter 1.0 was timed perfectly to follow up on configuring CI. Now it's easy to flutter upgrade with confidence.

I don't have the emulator running so you can ignore the connected device issue.
And that's it, app upgraded. This upgrade was minor as it was basically just updating the version number. But with tests and CI you can be confident that larger upgrades in the future won't break the app.


Along with version 1.0, Flutter had several other interesting announcements yesterday's Flutter Live event. Here are a couple that stood out to me:


2Dimensions announced Flare, a web based vector design and animation tool that lets designers work directly with the actual assets that will be in a Flutter app. I'm hoping this will integrate well with tools like Gallery.


CI/CD focused Nevercode launched Codemagic, the first CI/CD tool designed for Flutter developers. This looks great and I will probably be blogging about it in the future.


Flutter showed an experimental preview of running Flutter code in a web browser. Very early stage but Hummingbird looks like promising to support the web.

App progress

I didn't want to ignore the code base so I made some token changes removing the counter sample code.

Installing Storytlr the lifestreaming platform

" Storytlr  is an open source lifestreaming and micro blogging platform. You can use it for a single user or it can act as a host for many people all from the same installation." I've been looking for something like Storytlr for a few months now or at least trying to do it with Drupal . While I love Drupal and FeedAPI  I did not want to spend all that time building a lifestream website. So I've been playing around with Storytlr instead and found it very easy. Here is how I got it up and running on a Ubuntu EC2 server. You can also check out the official Storytlr install instructions . Assumptions: LAMP stack installed and running. Domain setup for a directory. MySQL database and user ready to go. Lets get started! Get the code : wget tar -xvzf storytlr-0.9.2.tgz You can find out the  latest stable release  on Storytlr's downloads page. Import the database : Within protected/install is database.sq

Sync is currently experiencing problems

Update : I now recommend you install Google Chrome  and  disable  the built in Browser as it supports encrypting all synced data. After picking up a gorgeous  Galaxy Nexus yesterday I was running into an issue where my browser data wasn't syncing to the phone. After a little Googling I found this is commonly caused by having all of my synced Chrome data encrypted instead of the default of only encrypting the passwords. These are the steps I went through to get my dat syncing again without losing any of it. The exact error I was getting was "Sync is currently experiencing problems. It will be back shortly." In Google Chrome open the personal stuff settings page by clicking this link or by opening the wrench menu, and click on "signed in with".  Hit "disconnect your Google Account" to temporarily disable syncing from your browser. Visit the Google Dashboard and "Stop sync and delete data from Google". I waite

A month of Flutter: a look back

Originally published on . This is it. 31 blog posts in 31 days. Writing  a month of flutter  has been a ton of work but also lots of fun and a good learning experience. I really appreciate how supportive and and positive everyone as been. Publishing experience For the series I've been posting on ,  DEV ,  my personal blog , and  Medium . After publishing to these sites, I would put the Bendyworks link on  Twitter ,  Reddit , and the  Flutter Study Group Slack . Posting to DEV was easy as they use Markdown just like the Bendworks blog. DEV also has built in support for a  series of posts  so it's easy to read the entire series. I did have to manually upload any embedded images. DEV also has a number of  liquid tags  for embedding things like GitHub issues that I didn't make as much use of as I should have. Blogger is rich text so it was easy to copy/paste the rendered posts. This would hotlink all the images though so I had to rem
