This is why flow invalidates type refinements at seemingly arbitrary times
class Test {
constructor() {
this.scrollView = {
flash: () => {
console.log(this);
},
doSomethingElse: () => {
console.log('*evil laugh*');

deecewan / generate-icons.sh
Last active April 27, 2018 01:31
Create icons for different flavours in a react native project. Uses bash because macOS comes with it
#!/usr/bin/env bash
typeset -a FLAVORS
####
# This creates icons in all the necessary sizes for a react native project
# To use, simply set the variables after this block
# Note, this expects your standard icon to be named `icon.png`, and
# all flavor icons to be named `icon_<flavor>.png`. For example,
# `icon_dogfood.png` and `icon_nightly.png`
