Using props in React style attribute

(I am using JSX with ES6 syntax) This works: render() { return ( <div style={{ width: '95%' }}></div> ) } This doesn't work: (why not?) Edit: It actually does work render() { return ( <div style={{ width: this.props.progress + '%' }}></div> ) } Edit: It works but the style value has to be a valid value else it will return the error. I use the state to create the style object and clean out the property with a regular expression in the constructor, so it will not be error-ing again because of invalid values. Here is my solution: import React, { Component, PropTypes } from 'react' export default

The argument type 'Object' can't be assigned to the parameter type 'ImageProvider<Object>'

I just updated to Dart2 and Flutter sdk: '>=2.12.0 <3.0.0' and now this if statement breaks: decoration: new BoxDecoration( shape: BoxShape.circle, color: Colors.blueAccent, border: Border.all( color: Colors.blueAccent, width: 20.0, style: BorderStyle.solid), image: new DecorationImage( fit: BoxFit.cover, image: myMarkerThumb != 'noImage' ? NetworkImage(myMarkerThumb) : AssetImage('assets/images/noImageAvailable.png'), ), ), The argument type 'Object' can't be assigned to the parameter type 'ImageProvider'. ), I'm just starting with flutter and have no idea where to look else.

What are the differences between using an HTML5 embedded video vs. an iframe with a YouTube link?

I'm debating whether or not to store a video on my server and call it through an HTML5 tag, or upload the video onto YouTube and use an iframe to embed the YouTube link. I'm not sure which would work more efficiently, or the differences between each one. What are the differences between using a HTML5 video tag and using a YouTube link and iframe tag?

Python: ignoring namespaces in xml.etree.ElementTree?

How can I tell ElementTree to ignore namespaces in an XML file? For example, I would prefer to query modelVersion (as in statement 1) rather than {http://maven.apache.org/POM/4.0.0}modelVersion (as in statement 2). pom=""" <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> </project> """ from xml.etree import ElementTree ElementTree.register_namespace("","http://maven.apache.org/POM/4.0.0") root = ElementTree
