Flutter 1.7 - what's new in the release of July 10, 2019
Not so long ago there was a release of Flutter on Google I / O, but, the Flutter team again rolled out a new version with interesting novelties, which I could not share.

It so happened that I plunged into development on Dart + Flutter. In addition to the fact that the application immediately runs on iOS and Android and, at the same time, the native code is generated, I liked the openness of the code (you can go deep into classes and watch the kernel code) and the openness of the community. As a contribution to the community, I publish this free retelling of an article about a new release from developers.

In principle, before the application migrated without problems on AndroidX , but now it is there right away. I had to migrate all my projects, therefore creating new ones I plan to use this feature. To do this, when creating an application, simply use the
Starting August 1, 2019, Android applications that use native code and use Android 9 Pie will have to provide a 64-bit version in addition to the 32-bit one. Flutter already supports the creation of 64-bit Android applications. But, starting with version 1.7, support has been added to create Android App Bundles for 2 versions at once.
Personally, I ran into this a week ago, when, when generating an executable .apk file for Android, when instead of 12 MB, it suddenly became 25 MB. After that I generated Bundle and hurray, the size is normal again.
What is app bundle here ?
Since Google, if I understand correctly, goes to the concept of surfaces, instead of the concept of applications, they pay much attention to widgets that represent the functionality of the user.
In this release, a new slider for ranges has been added (most likely for use in their temperature devices), into which we, as developers, can climb and make our beautiful pieces.
Although I am a developer, I also understand the importance of fonts. Moreover, applications are written immediately for iOS and for Android. In the new release, improved work with the text for iOS . A big upgrade of rich typography support has been made - including different digit styles, style sets, etc. An example on github .
I often hang out for a long time with examples to get programming techniques from there or just copy the code. A wonderful feature, the code can create a project from the example and immediately make Run. The Flutter team wrote that the number of such examples is increased.
If an example can be generated this way, then an additional bookmark appears.
That's all, to all good coding :) Also, my friends and I plan to do one mitap per month for Flutter, in order to have fun and be pumped at the same time. To whom it is interesting to join - write in the comments or in a personal.

flutter create --sample=material.AppBar.1 mysample
If an example can be generated this way, then an additional bookmark appears.
