Use the DisplayName from the Googlesignin instance in the Chatmessage class to set the _name variable. class Chatmessage extends Statelesswidget {//... @override Widget build (Buildcontext context) {return new Sizetransition (//... child:new Container margin:c

This article lists the issues that are encountered when using flutter for project development, and how to integrate flutter into existing projects using the Flutter module, and analyzes its rationale. Recently in a Business project, the full use of the flutter, which the pit, only written by the people can appreci

This article mainly introduces flutter related things, including fuchsia, Dart, flutter features, installation, and overall architecture. 1. IntroductionFlutter, as Google's recently launched cross-platform development framework, attracted a lot of attention once it was launched.

What is flutter? He is Google based on the dark language open source cross-platform development dependency. As with the fire reactive native, a set of code can implement two different platform apps. So why introduce flutter instead of reactive Native in the domestic fire. Specifically, you can look at this article. I'm not here to explain more. Previously flutter

On Google I/O ' 17, Google introduced us to flutter--a new open source library for creating mobile apps.As you can imagine, flutter is able to help create a cross-platform mobile application solution with a beautiful UI interface. Flutter's interface design is similar to a Web application, so you can find a sense of familiarity like using html/css from flutter.Google says:

1. Why add pooling (pooling) to the convolutional networkIf you only use convolutional operations to reduce the size of the feature map, you will lose a lot of information. So think of a way to reduce the volume of stride, leaving most of the information, through pooling to reduce the size of feature map.Advantages of pooling:1. Pooled operation does not increase parameters2. Experimental results show that the model with pooling is more accurateDisadvantages of pooling:1. Because the stride of t

1. Preface I wrote an article about the first experience of flutter. After a while, I changed my computer, re-installed androidstudio, and continued to build a flutter. Then I used the plug-in for a while to complete the configuration, then I created a project with the AS, good guy, and reported an error directly.

Now the way to develop the App is very many, native, reactnative, flutter is a good choice. Do you have any concerns about the size of the APK that is compiled and built using different methods? This article is a simple Hello world App, to see the different frameworks, the size of the compiled APK, what is the difference. Of course, the context of this article is a simple Apk, in fact, only partially explain the problem, do you think?-Incense Ink Film

Google's new DART-based mobile development framework, flutter, is actually the previous Sky SDK, a mobile development framework based on the Dart language, a competitor of react native.Initially viewed, is a dart-based language inspired by the react Native, a high-performance native UI that supports the refresh rate of + FPS, and supports the material Design's mobile development frameworkOfficial website http://flutter.io/Https://github.com/

The hardware-related parts of flutter have always been very painful. There are basically two kinds of scenarios, write it yourself, or wait out the relevant library.In a recent project, the camera needs to be customized. Having experienced the development of the relevant modules, we know that this need is not simple, and it is the beginning of this cross-platform solution.The demand is coming, how to do? Then you can only bite the bullet. Go to the pu
