It is a [UID][1] which can be used by the website operator (and Cloudflare support) to potentially debug issues. The ray id is actually returned in the headers of most requests through Cloudflare, just not as visibly as what you see in the case of I&#39;m under attack mode.

Without padding I get this result:

[![no padding][1]][1]

With something like this

    Padding(padding: EdgeInsets.all(20.0), child: TextField())

I get the following result:

[![with padding][2]][2]

It might be a bit hard to see, but you only have to look at the red badge across the edge to realise what I mean. 

I would like to only move the text with my padding, but in reality the whole `TextField` has the padding applied, i.e. that the underline moves with the padding, but I would like to have the underline still go across the whole view, that only the text inside the `TextField` is affected by the padding.

How do I only apply padding to the text in a TextField in Flutter?

I have upgraded my Android Studio and I found many problems in the latest version.

Although many similar questions exist, I checked the answers to all and none of them worked for me!

Here is the error I&#39;m facing while compiling the code:  

&gt; Program type already present:
&gt; android.support.v4.app.BackStackRecord$Op
&gt;         Message{kind=ERROR, text=Program type already present: 
&gt;         android.support.v4.app.BackStackRecord$Op, sources=[Unknown source file], tool 
&gt;     name=Optional.of(D8)}

Here is my gradle file:

**project**:

    // Top-level build file where you can add configuration options common to 
   
    all sub-projects/modules.

    buildscript {
    
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath &#39;com.android.tools.build:gradle:3.1.0&#39;
        

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
        }
     }

     allprojects {
     repositories {
        google()
        jcenter()
        maven {
            url &quot;https://jitpack.io&quot;
              }
         }
    }

    task clean(type: Delete) {
    delete rootProject.buildDir
    }


**app**:

    apply plugin: &#39;com.android.application&#39;

    android {
    compileSdkVersion 27
    defaultConfig {
        applicationId &quot;com.alcantara.bugismart&quot;
        minSdkVersion 15
        targetSdkVersion 27
        versionCode 1
        versionName &quot;1.0&quot;
        testInstrumentationRunner 
    &quot;android.support.test.runner.AndroidJUnitRunner&quot;
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile(&#39;proguard-android.txt&#39;), 
    &#39;proguard-rules.pro&#39;
                }
               }
    }

    dependencies {
        implementation fileTree(dir: &#39;libs&#39;, include: [&#39;*.jar&#39;])
        implementation &#39;com.android.support:appcompat-v7:27.1.1&#39;
        implementation &#39;com.android.support.constraint:constraint-layout:1.0.2&#39;
        testImplementation &#39;junit:junit:4.12&#39;
        androidTestImplementation &#39;com.android.support.test:runner:1.0.1&#39;
        androidTestImplementation &#39;com.android.support.test.espresso:espresso- 
        core:3.0.1&#39;
        implementation &#39;com.github.ViksaaSkool:AwesomeSplash:v1.0.0&#39;
    }


You can tell me if there is anything else to add to understand what I&#39;m doing or where I&#39;m wrong.

Program type already present: android.support.v4.app.BackStackRecord

Every time I visit a website that is using Cloudflare&#39;s Under-Attack-Mode, it shows me the usual text telling me to wait a few seconds until Cloudflare verified I am not a bot. Every time I reload the page it changes my current Ray ID.

What is the purpose of a Ray ID? Is it some kind of session ID?
