Flutter for Single-Page Scrollable Websites with Navigator 2.0




















Image







  Single page scrollable websites are everywhere. In this website design pattern, all the content is presented in one long-scrolling layout that contains multiple sections. Visitors can scroll or jump to a section by clicking buttons of a sticky menu. This pattern is a good fit for small content such as brochure websites, software library documentation, portfolios, and landing pages that are used to convert users [ 1 ]. Designers also love this pattern because it is simple, clean, and enables cool scroll animations. Jetbrains Mono single-page scrollable website Hive docs multi-page scrollable website In this series of articles, we will explore how to build a  single-page scrollable website  using Flutter.

       A Data Science Portfolio is More Valuable than a Resume                Benjamin Obi Tayo Ph.D.  Following      Nov 20  · 5 min read                                    D ata Science is a practical field. Hands-on skills are very important especially when you are interested in working outside academia as a practicing data scientist.   In academia, you need more theoretical and research skills. While in-depth knowledge in the theoretical foundations of data science is important, as a practicing data scientist, hands-on experience is very crucial and one way to showcase you hands-on skills is via building a very great portfolio. Companies interested in hiring you would definitely be asking you for a portfolio, as it gives evidence of your strengths in fundamental data science concepts.   While a data science resume is important, a data science portfolio is more valuable than a resume. This article will discuss 3 important platforms that can be used for portfolio buildi...

Better File Storage in Oracle Cloud

  Use Oracle Application Express with Oracle Cloud Infrastructure REST APIs to upload, download, and manage big files in Oracle Cloud.   By Adrian Png   November 27, 2019   Oracle Cloud Infrastructure  provides a comprehensive suite of REST APIs for accessing and managing cloud resources. For example, administrators can use REST APIs to create and manage autonomous databases and initiate backups.   Oracle Application Express (Oracle APEX)  makes working with REST easy. The  APEX_WEB_SERVICE  package, available since Oracle APEX 4.0, provides developers with a function for consuming REST APIs. Oracle APEX 5.0 introduced the  APEX_JSON  package, allowing easy parsing of JSON responses. Oracle APEX 18.1 introduced the Web Source Module (WSM), which enables developers to access REST services and use the data in APEX components such as reports, interactive reports, and interactive grids.   These features, when used together with Oracle Cloud Infrastructure REST ...
