Features #

• Network inspector
• Shared preferences inspector
• Redux inspector
• Database Browser

Quick Start #

Prerequisites #

Before starting make sure you have:

• Installed Flipper Desktop

Installation #

Add this to your package's pubspec.yaml file:

dependencies:
  flutter_flipperkit: ^0.0.22

Or

dependencies:
  flutter_flipperkit:
    git:
      url: https://github.com/blankapp/flutter_flipperkit
      ref: master

Android

Change your project files according to the example:

android/app/build.gradle:

android {
-    compileSdkVersion 27
+    compileSdkVersion 28

    defaultConfig {
-        targetSdkVersion 27
+        targetSdkVersion 28
    }
}

android/app/gradle.properties:

+android.useAndroidX=true
+android.enableJetifier=true

android/settings.gradle:

...

plugins.each { name, path ->
    def pluginDirectory = flutterProjectRoot.resolve(path).resolve('android').toFile()
    include ":$name"
    project(":$name").projectDir = pluginDirectory

+    if (name == 'flutter_flipperkit') {
+        include ':flipper-no-op'
+        project(':flipper-no-op').projectDir = new File(pluginDirectory, 'flipper-no-op')
+    }
}

...

iOS

Open ios/Runner.xcworkspace Add a empty Swift file (e.g Runner-Noop.swift) into Runner Group And make sure the Runner-Bridging-Header.h file is created.

Change your project ios/Podfile file according to the example:

# Uncomment this line to define a global platform for your project
-# platform :ios, '8.0'
+platform :ios, '9.0'

# CocoaPods analytics sends network stats synchronously affecting flutter build latency.
ENV['COCOAPODS_DISABLE_STATS'] = 'true'

project 'Runner', {
  'Debug' => :debug,
  'Profile' => :release,
  'Release' => :release,
}

def parse_KV_file(file, separator='=')
  file_abs_path = File.expand_path(file)
  if !File.exists? file_abs_path
    return [];
  end
  generated_key_values = {}
  skip_line_start_symbols = ["#", "/"]
  File.foreach(file_abs_path) do |line|
    next if skip_line_start_symbols.any? { |symbol| line =~ /^\s*#{symbol}/ }
    plugin = line.split(pattern=separator)
    if plugin.length == 2
      podname = plugin[0].strip()
      path = plugin[1].strip()
      podpath = File.expand_path("#{path}", file_abs_path)
      generated_key_values[podname] = podpath
    else
      puts "Invalid plugin specification: #{line}"
    end
  end
  generated_key_values
end
