rxdart_codemod's Introduction

rxdart_codemod

A utility for updating RxDart code from 0.22.x to 0.23.x.

RxDart 0.23.x removes the Observable class by taking advantage of extension methods. This change requires many small refactors, mostly around calling slightly different constructors.

This codemod runs through your codebase and performs these refactors so you don't have to!

Installation

rxdart_codemod provides an executable via dart global packages.

In your terminal:

pub global activate rxdart_codemod

Usage

cd path/to/your/code
pub global run rxdart_codemod:22_to_23

Arguments

    --[no-]recursive    Apply updates to Dart files in the current directory and all subdirectories recursively.
                        (defaults to on)

    --[no-]classes      Use Stream classes instead of Rx factories. Example: "TimerStream" instead of "Rx.timer"
                        (defaults to off)

-h, --help              Prints the help menu

rxdart_codemod's Issues

Version solving failed

When trying to run pub global activate rxdart_codemod , I get the following error:

Resolving dependencies... 
The current Dart SDK version is 2.4.0.

Because pub global activate depends on rxdart_codemod any which requires SDK version >=2.5.0 <3.0.0, version solving
  failed.

if I run flutter --version, I get the version to be:

Flutter 1.12.13+hotfix.8 • channel stable • https://github.com/flutter/flutter.git
Framework • revision 0b8abb4724 (34 hours ago) • 2020-02-11 11:44:36 -0800
Engine • revision e1e6ced81d
Tools • Dart 2.7.0

I have no idea what the problem is, but I REALLY need to get my Observable.combineLastest2(first, second, (first, second) => [...first, ...second]) to the new StreamExtensions
